PDF Summary:The Story of Philosophy, by Will Durant

Tracing the progression of Western philosophy, The Story of Philosophy by Will Durant offers profound insights into the origins and evolution of rationality, self-reflection, and moral inquiry. The book examines the contrasting perspectives of influential thinkers who have shaped humanity's understanding of nature, being, and existential purpose.

From the natural philosophers of ancient Greece to the Enlightenment era's advocates of reason, Durant unveils the fundamental questions and core tenets that drove seminal thinkers like Socrates, Plato, Aristotle, Hobbes, Locke, and Kant. As philosophical currents shifted between materialism and idealism, Durant immerses you in the discourse of opposing views on the primacy of logic, empiricism, ethics, and moral imperatives.

(continued)...

Durant elucidates how our inner moral compass firmly commands us to act in alignment with principles that could be adopted universally, referring to this as Kant's categorical imperative. This universal principle insists that our actions should be guided by rules that all rational entities could adopt without leading to contradictions or their own demise. Kant contends that an intrinsic principle, which is not acquired empirically, is embedded within the moral self, serving as an unwavering benchmark for ethical actions.

The idea that "good will" underscores the significance of remaining true to ethical values rather than focusing on the consequences of one's deeds.

Durant highlights Kant's emphasis on the primacy of the "good will", arguing that an action is truly moral only if it is performed out of reverence for the moral law, and not because of any anticipated consequences. The value of an action is gauged by the motivation driving it, especially the commitment to maintain the categorical imperative's tenet, regardless of any ensuing external outcomes or personal gains. Durant explains, places greater value on the moral integrity of the will itself rather than the physical consequences of an action, underscoring the significance of fulfilling one's obligations and the motivations behind them instead of the outcomes or happiness they produce; he supports the idea of maintaining our duties even when the outcomes may be adverse.

Our moral compass, rather than physical proof, bolsters our belief in the divine, our liberty of choice, and the notion of an afterlife.

Durant elucidates how Kant's formulation of the categorical imperative, along with his focus on the significance of good will, underscores the essentiality of ethical guidance and bolsters the belief in a divine entity, human self-determination, and the persistence of existence after death. Our ethical perceptions are founded on these concepts, despite their lack of theoretical validation. Our unwavering commitment to moral principles, despite possible consequences, suggests that our choices are self-determined, indicating a will that transcends the deterministic processes of the physical world. Our moral convictions lead us to expect that virtuous actions will receive acknowledgment and misdeeds will be met with repercussions, even if these results are not observed in our lifetime; Durant proposes that these expectations hint at an afterlife where justice prevails, overseen by a divine being who guarantees this ultimate universal balance.

Practical Tips

• You can reflect on your decision-making process by journaling about times when you relied on reason versus emotion. Write down a recent decision you made and analyze whether you were guided by logic or your feelings. This can help you understand your personal balance between Enlightenment values of reason and Rousseau's emphasis on emotion.
• Experiment with organizing your perceptions by creating a mind map after a complex experience. For instance, after attending a lecture or watching a documentary, draw a mind map to visually organize what you've learned. This can illustrate how your mind works to create coherent concepts from your perceptions, akin to Kant's ideas.
• Practice ethical decision-making by considering the universal applicability of your actions. Before making a decision, ask yourself if you would be comfortable if everyone made a similar choice. This aligns with Kant's categorical imperative and can help you assess the moral implications of your actions in everyday life.

Nietzsche's philosophical thought and its developmental essence.

Intellectual and Cultural Lineage

The application of Darwinian principles to ethical considerations implies that robustness is deemed the most crucial attribute in the struggle for existence.

Durant demonstrates how Nietzsche, influenced by Darwin's theories, sought to apply the principles of survival competition and natural selection to the realm of morality. Life is an ongoing struggle for existence, with the fittest emerging victorious, prompting Nietzsche to declare that the essential quality is fortitude, and that the only fault lies in frailty. From this viewpoint, virtues are associated with traits that enhance the well-being and success of both the person and humankind, while anything that diminishes or hinders the affirmative expression of life is deemed harmful.

Observers have noted that even after embracing Darwinian theories, thinkers continue to uphold the principles of Christian morality, despite having abandoned the typically associated religious foundations.

Durant highlights Nietzsche's criticism of some intellectuals who, although they rejected the religious foundations of Christianity, still clung to an ethical system that was influenced by that very faith, including philosophers like Spencer and Mill. Nietzsche argued that when philosophers dismiss the notion of a supreme being and an everlasting soul, they inadvertently weaken the logical underpinnings that support traditional moral values like humility, compassion, and selflessness—values that are beneficial for survival solely in a cosmos governed by a benevolent deity who encourages modesty and curbs pride. Nietzsche argued that his philosophical peers failed to comprehend the full implications of Darwin's theory, resulting in the creation of a conceptual structure that would, in the end, weaken Europe's intellectual vigor.

Schopenhauer's philosophical stance, which places the will at the forefront and adopts a generally pessimistic view of existence, has been highly influential.

Durant illustrates how Nietzsche's thought was deeply influenced by Schopenhauer's pessimistic philosophy and the concept of the will. Durant contends that Nietzsche's view of the world, driven by an irrational "will to live" that ceaselessly strives for self-preservation and expansion, drew significant inspiration from the ideas put forth by Schopenhauer. Nietzsche's initial contributions were profoundly shaped by the widespread unrest and disillusionment that characterized nineteenth-century Europe. "The Birth of Tragedy" presented a somber perspective on human life, characterized by an unending cycle of effort, anguish, and demise.

The esteem for Bismarck's forceful and uncompromising political strategy.

Durant examines Nietzsche's respect for Bismarck's decisive and robust approach to politics, often encapsulated by the phrase "iron and blood." Nietzsche viewed Bismarck as the embodiment of a new ethical framework that prioritized power and authority, recognizing the realities of political life while rejecting the unrealistic and impractical illusions often linked with democracy, in favor of a resolute and morally neutral exercise of power. Nietzsche interpreted the unification of Germany under Bismarck, fueled by its military might and economic prowess, as a recognition of the age-old "master morality," which triumphed over the collective moral principles embodied in Christianity.

The development of a person's traits and skills.

Early religious piety and its influence on his later critique of Christianity

Durant highlights the inconsistencies within Nietzsche's development, both intellectually and personally, observing how his early profound religious beliefs greatly shaped his subsequent thorough examination of Christian teachings. Nietzsche grew up in a household where daily life was firmly founded on intense religious commitment and strong moral fervor. Durant portrays the individual who would eventually be known as the "Anti-Christ" as having a formative period heavily influenced by scriptural stories, frequently displaying intense emotions and a passionate dedication to the moral principles imparted by them. Christianity's teachings had a profound impact on his intellectual growth, providing him with a deep understanding of its principles and a keen sense of the emotional power of faith. His close but adversarial relationship with Christianity fueled the unyielding critiques he subsequently articulated in his written works, which were directed at the religious beliefs.

The search for new guidance resulted in the discarding of traditional moral principles and religious beliefs.

Nietzsche's journey of the mind and spirit, characterized by his rejection of traditional ethics and religion, mirrors his search for a new sacred value to occupy the emptiness created by the deity he disavowed early in life. Durant observes that Nietzsche immersed himself in philosophy and classical philology, motivated by the emptiness and meaninglessness of life after the waning of religious faith, seeking new standards to determine values and judge human behavior. He explored the doctrines of ancient Greek philosophers, including Schopenhauer, and found that these perspectives often emphasized life's intrinsic melancholy instead of providing a solution for sorrow. Displeased with conventional moral principles, Nietzsche sought to create a new ethical system that would exalt life and support the supremacy of the powerful over the less powerful.

Initially drawn to yet eventually disenchanted with the philosophical and aesthetic principles associated with Wagner.

Durant chronicles the evolution of Nietzsche's perspective, from an early passion for Wagner's creative and ideological tenets to a deep-seated disillusionment. In his formative years, Nietzsche was profoundly shaped by the idea of reviving the spirit of the ancient Greeks' Dionysian character through a German artistic renaissance, as exemplified in Wagner's music. He saw in Wagner a cultural hero, a man who dared to challenge the conventions of his time and who sought to create a new and more vital art form. Nietzsche's evolving philosophy led him to recognize elements in Wagner's compositions that conflicted with his principles, particularly the growing presence of Christian themes and a focus on dramatic aspects that did not align with his preference for a more nuanced and intellectual style. Nietzsche saw the integration of Christian themes in Wagner's Parsifal as a betrayal of the robust, tragic values that had been essential to his previous works, which ultimately resulted in the dissolution of their friendship.

His waning health profoundly influenced his praise for strength and vitality.

Durant depicts Nietzsche's withdrawal into seclusion as being driven by his declining health and diminishing eyesight, factors that heightened his valuation of strength and vitality as the paramount virtues. His fragile health, frequently afflicted by discomfort and intense migraines, coupled with deteriorating eyesight which forced him to abandon his beloved examination of classical literature, deepened his awareness of life's difficulties and highlighted the limitations imposed by our physical form. He passionately accepted life, with its inherent struggles and sorrows, and he highly valued robustness and vigor as the utmost ethical ideals. The idea of the Übermensch embodies a paramount being who rises above the common weaknesses and moral decay of present-day society.

Central Philosophical Concepts

The birth of tragedy in Greek culture was a result of the intense conflict between the instinctive Dionysian aspects and the rational, orderly characteristics of Apollo.

Durant summarizes that through the interplay of Dionysian and Apollonian forces, Greek art and literature developed, a concept Nietzsche grasped profoundly in "The Birth of Tragedy." Durant characterizes Dionysus as the personification of life's primal energies, which manifest through the unrestrained manifestation of emotions, yearnings, and the ecstatic experiences encountered in music, dance, and theater. In contrast, Apollo represents the harmonious structure, clarity of thought, and refined beauty present in visual arts and epic poetry, underscoring the significance of transparency, orderly structure, and intellectual rigor. Nietzsche argues that Greece's most sophisticated art was born from the harmonious equilibrium of contrasting forces, specifically the dynamic interaction of Dionysian passion and Apollonian order.

An examination of the intellectual lineage rooted in rationalism, as it casts light on Socrates, symbolizes a civilization on the wane.

In "The Birth of Tragedy," Nietzsche views the rise of Socratic thinking as a sign of cultural decline, moving away from the passionate Dionysian spirit of previous eras. Nietzsche argued that the Greeks' emphasis on logic, reason, and intellectual superiority stifled their natural creative impulses, leading to a weakened will and a growing tendency to value complex theoretical frameworks over the raw realities of existence. Greek culture faced a decline during the period that gave rise to philosophers like Socrates, Plato, and Aristotle, who personified the concept of 'theoretical man'.

A "Superman" is defined as an individual who transcends conventional moral values, embodying strength, intelligence, and self-esteem.

Durant explores Nietzsche's later philosophical ideas, particularly focusing on the Übermensch as a central character in Thus Spake Zarathustra. Durant suggests Nietzsche introduced the idea of the Übermensch as a response to the prevalent ordinariness and deterioration of his era, symbolizing an evolved human type that surpasses traditional ethical limitations and embodies an enhanced combination of strength, intelligence, and dignity. This remarkable individual surpasses the conventional moral standards associated with Christianity and democracy, which Nietzsche believes are designed to protect the weak and restrain the strong; he establishes novel principles, dictates his own conduct, and embodies a being that operates in a sphere beyond the usual bounds of ethicality.

Master morality praises the qualities associated with power and control, while slave morality values humility and compliance.

Durant examines how Nietzsche formulated the ideas of "master morality" and "herd morality" in his writings. In his works titled "Beyond Good and Evil" and "The Genealogy of Morals." Durant describes master morality as a trait of influential and powerful individuals who craft their own ethical principles, thereby distinguishing themselves from society's conventional norms. The philosophy praises the pursuit of dominance and self-discovery, viewing life as a competition for power and self-affirmation. Morality within the group, conversely, reflects the norms of individuals who seek safety through group unity and adhere to values entrenched in tradition and set forth by community leaders. It emphasizes the significance of humility, understanding, and selflessness, traits that bolster the community's resilience, though Nietzsche views these as ultimately undermining life's affirmation.

Aristocracy was esteemed, while democratic values were often overlooked.

Durant suggests that Nietzsche's preference for aristocracy over democracy is rooted in his belief that men are fundamentally unequal, closely linked to his concept of an innate drive for dominance. Nietzsche considered democracy to be a framework that raises the status of the powerless at the expense of the powerful, interpreting it as a form of rule by the masses that embodies a shared ethical perspective deeply rooted in European philosophical traditions. The individuals who are most adept, possessing both energy and intellect, play a pivotal role in forming an advanced society governed by an aristocratic system.

Human behavior is fundamentally driven by an inherent quest for dominance and the exertion of influence.

Durant clarifies Nietzsche's later work by proposing that the primary motivator for all human behavior, and perhaps for everything that exists, is the desire for dominance and control. The pursuit of supremacy transcends mere political or economic desires, reflecting a profound philosophical tenet of self-assertion and proliferation; it signifies an intrinsic impulse for development and innovation in all facets, striving to exceed limits and enhance one's vigor and robustness. Nietzsche argues that all human actions, whether they are sophisticated intellectual endeavors or crude displays of dominance, stem from a fundamental urge to excel, dominate, and introduce new ideas.

The concept of eternal recurrence suggests that events are fated to repeat themselves cyclically, due to the limited range of possible events over the expanse of infinite time.

Durant examines the idea proposed by Nietzsche that the universe is trapped in an endless loop of recurrence, with every event destined to happen again due to the limited ways in which matter can arrange itself and the infinite nature of time. Nietzsche addressed the existential challenge of a godless universe by introducing an idea that, while rooted in ancient Stoic thought, was substantially developed through the contributions of Schopenhauer. In a world where this life is the entirety of our existence, devoid of celestial realms or eternal damnation, absent of ultimate reckoning or heavenly recompense, it is imperative that we pursue significance by wholeheartedly accepting the most brutal truths of our existence, by acknowledging the certainty of anguish and the cessation of life, and by recognizing the poignant splendor of a universe where each instant and each existence perpetually recurs, in an unceasing cycle.

Context

• Nietzsche criticized intellectuals who rejected religious beliefs but still adhered to Christian moral values. He argued that by dismissing the foundations of Christianity, they weakened the logical basis for upholding traditional moral principles like humility and compassion. Nietzsche believed that embracing Darwinian principles should lead to a reevaluation of moral values, emphasizing strength and fortitude over traditional Christian virtues. This critique aimed to challenge the inconsistency he saw in intellectuals who retained Christian ethics without the religious framework.
• In Nietzsche's philosophy, master morality is associated with individuals who define their own values based on strength and power, while slave morality is linked to those who adopt values of humility and obedience. Master morality emphasizes self-assertion and the pursuit of individual excellence, viewing life as a competition for power. Slave morality, on the other hand, values traits like compassion and meekness, focusing on community cohesion and shared values. Nietzsche critiques slave morality for hindering the affirmation of life and undermining the potential of exceptional individuals.
• Nietzsche's preference for aristocracy over democracy stems from his belief in inherent human inequality and a natural drive for dominance. He viewed democracy as a system that uplifts the weak at the expense of the strong, contrasting it with an aristocratic society where the most capable individuals lead. Nietzsche believed that a society governed by an aristocratic elite would better reflect the natural order of dominance and excellence.
• Nietzsche's concept of eternal recurrence posits that all events in the universe, including our lives, will recur infinitely in an unending cycle. This idea challenges individuals to embrace the present moment fully, as every action and decision would be repeated eternally. It serves as a test of one's acceptance of life's joys and sorrows, urging a profound affirmation of existence. The concept emphasizes living authentically and making choices as if one would willingly relive them for eternity.

A Synopsis of the Progressive Development in Philosophical Thought

Philosophical contemplation originated in ancient Greece.

The emergence of explanations for the universe based on natural phenomena, transcending mythological narratives and supernatural forces.

Durant observes that the ancient Greeks are acknowledged for initiating the journey of Western philosophy, marking a significant shift from earlier societies through their promotion of comprehending the cosmos based on natural phenomena, thereby moving away from the longstanding mythological and supernatural justifications that dominated human thought for centuries. Philosophers like Thales and Anaximander explored the fundamental nature of being, concentrating on the properties of matter, the principles of motion, and the mechanisms of change, aiming to explain the cosmos through natural principles rather than ascribing it to divine intervention. The emphasis on identifying causes rooted in nature and utilizing logical analysis marked a profound shift in human thinking, laying a robust groundwork for the progression of scientific and philosophical exploration.

The initial thinkers preceding Socrates were engaged in a quest to understand the fundamental nature of being.

Durant explores how the early Greek philosophers sought to identify the arche, the fundamental origin that serves as the foundation for all existence. Thales proposed that water, due to its essential role in sustaining life and its capacity to change into various states, constitutes the primary substance. Anaximander theorized that the "apeiron," a boundless and indeterminate primal matter, served as the fundamental abstract source from which contrasting elements like heat and cold or moisture and aridity separated and established their distinct identities. Heraclitus suggested that fire represents the fundamental substance, illustrating the constant and ever-changing essence of life to highlight the unending transformation of the world. These endeavors, though sometimes based on conjecture and not always supported by empirical evidence, signify the initial strides taken by Western philosophy in its journey to comprehend the cosmos through reason.

Socrates emphasized the importance of leading a life that is subject to scrutiny and grounded in moral excellence through his concentration on ethical and self-reflective inquiries.

Durant highlights Socrates' pivotal role in shifting the focus of Greek philosophical exploration from probing into the origins and nature of the world to an in-depth analysis of ethical conduct and the intricacies of human cognition. Socrates, as portrayed by Durant, placed a greater emphasis on leading a life of virtue than on delving into the underlying nature of existence. He famously declared that a life that lacks introspection holds no value and committed himself to dialogues with Athens' youth about their beliefs and values, promoting the development of a virtuous character through self-examination and critical thought. He emphasized the importance of defining one's concepts and seeking out universal moral principles, thus laying a groundwork that would later be built upon by Plato and Aristotle in their own ethical philosophies.

Plato conceived of a society under the rule of kings who were also philosophers, with a foundational concept of Forms.

Durant clarifies that Plato's concept of ideal archetypes seeks to reconcile Heraclitus's focus on perpetual flux with Parmenides' view on immutable being. Plato proposed the existence of a realm where eternal, unchanging Forms or Ideas serve as the perfect prototypes for the transient and imperfect things we discern through our senses. The Forms, Durant elucidates, existed in a realm transcending temporal existence and the physical, comprehended through intellectual faculties instead of through the senses. Plato's "The Republic" describes a utopian society governed by philosopher-kings whose deep comprehension of the Forms uniquely qualifies them to guide and manage the state to everyone's advantage.

Aristotle's contributions were pivotal in structuring various domains of knowledge, including but not limited to logic, metaphysics, psychology, ethics, and the study of governance.

Durant emphasizes the significant influence of the ancient Greek philosopher in structuring human knowledge, instituting logic as a tool for clear thinking, delving into the essential elements of being to broaden metaphysical exploration, and offering actionable guidance for individual conduct as well as in shaping societal norms and governance. Aristotle, diverging from his mentor's approach, prioritized insights derived from empirical evidence over the concept of unalterable Forms. He championed a method that emphasized examining specific details meticulously prior to developing overarching theories. His emphasis on empirical investigation and systematic classification laid the groundwork for subsequent scientific pursuits, and his ethical direction, emphasizing balance and the pursuit of happiness through the development of virtuous habits, has profoundly influenced Western thought.

Europe's legacy of philosophy.

Scientific progress has driven the adoption of a materialistic perspective and the approach of mechanistic reasoning.

Durant maps the rise of philosophical concepts, emphasizing how theories centered on materialism gained prominence throughout Europe, particularly in the 17th and 18th centuries, driven by advancements in science and technology. The progress in science, particularly in the realms of physics and chemistry, along with the transformative period of the Industrial Revolution, nurtured a widespread belief that all aspects of reality, including life and consciousness, could one day be understood through the laws that dictate physical phenomena and the behavior of matter. Philosophers, including Hobbes and La Mettrie, compared the universe and human beings to intricate machines, operating under deterministic principles.

Hobbes depicted the fundamental nature of being as a collection of indivisible particles and voids, while Locke's psychological theories were grounded in empirical observation.

Durant emphasizes the critical roles of Thomas Hobbes and John Locke in advancing a philosophy that is both materialistic and mechanistic. Hobbes, influenced by Galileo's physics, suggested the universe consisted solely of moving material particles within a vacuum, all conforming to mechanical laws. He approached psychology with the viewpoint that thoughts and sensations are akin to the brain's particle dynamics. Locke established the foundation for empirical psychology with the assertion that our comprehension originates from experiences of the senses. Upon its arrival in the world, the mind resembles a blank canvas, recording the events and experiences of life as impressions.

Spinoza was of the opinion that all of existence is embodied within a singular entity, contrasting with Descartes's perspective on the separate characteristics of mind and matter.

Durant examines the contrasting foundational perspectives of René Descartes and the equally distinguished thinker Baruch Spinoza, two European philosophers of the 17th century who were deeply dedicated to the tenets of mathematics and logical deduction. Durant presents a viewpoint where the divine and the natural are interwoven, both representing aspects of an existence that is both singular and limitless. He theorized that all events, encompassing both mental and material realms, stem from a single underlying substance that is regulated by the immutable laws of this divine element. Descartes delineated the realms of thought and material substance, asserting that their interaction necessitated divine involvement.

The movement of the Enlightenment, which challenged unfounded beliefs and championed the supremacy of logical reasoning, was exemplified by thinkers such as Voltaire and the creators of the Encyclopaedia.

Durant describes the 18th-century Enlightenment as a pivotal era that emphasized logical reasoning, placed significant emphasis on learning through experience, and celebrated individual independence, which culminated in the achievements of Voltaire and the founders of the Encyclopaedia. Enlightenment challenged the prevailing doctrines and social structures, particularly the dominant role of the church and the firm proclamations of religious knowledge, motivated by advancements in science and mathematics, as well as the growing prosperity and sway of the bourgeoisie. They were proponents of embracing diverse viewpoints, supported the freedom of thought and expression, and upheld a global outlook, firmly believing that humanity's progress and satisfaction could be achieved by employing rational thought and the quest for understanding.

Kant challenged materialism with the philosophical stance that our capacity for reason is limited by certain boundaries, and he proposed that our moral compass is the basis for our beliefs.

Durant illustrates that Immanuel Kant formulated his critical philosophy as a counter to the Enlightenment's strong inclination toward a materialistic and mechanistic interpretation of the universe. Kant, deeply influenced by Hume's skepticism, sought to reconcile rational thought with spiritual belief. Kant argued that pure logic, when attempting to explore the essential elements of being beyond what is experienced, inevitably faces contradictions and dead ends. Kant proposed a transformative shift in philosophical thought, comparable to Copernicus's impact on astronomy, by positing that the mind is not passively molded by external influences but rather it actively organizes and assigns meaning to our experiences through its inherent sensory and cognitive constructs. He contended that the foundation of religious belief should not rely on theoretical evidence, but rather on the categorical imperatives of moral consciousness.

Schopenhauer emphasized the intrinsic drive to persist, coupled with his characteristically pessimistic viewpoint regarding existence.

Durant delves into Schopenhauer's conviction that an insatiable and unstoppable force drives every being, a force he terms the "will to live." Schopenhauer's philosophical outlook contends that life is fundamentally a struggle against suffering, characterized by a perpetual cycle of desire, disenchantment, and death, contrasting sharply with Hegel's optimistic perspective on reason. He believed that the will, driven by an unyielding desire for self-preservation and improvement, merely uses the intellect as an instrument. Attaining a state of calm and avoiding unease can be realized by letting go of cravings and overcoming the urges that fuel our deepest yearnings.

Hegel's approach to deciphering the advancement of history employs a dialectic process that evolves from a foundational idea to its contradiction, culminating in a synthesis.
