Perspectives on Life's Meaning from Three Iconic Philosophers

The inquiry, 'What is the meaning of life?' is both an age-old philosophical debate and a relatively modern idea. Although the pursuit of life's purpose predates even the ancient Greek philosophers, it was Arthur Schopenhauer in the mid-1800s who formally posed the question of der Sinn des Lebens (German for 'the meaning of life'). He argued that life's essence lies in the 'will to live,' an innate drive, and that tranquility is achieved by overcoming this will. Numerous philosophers have tackled this profound question, offering diverse insights that can guide us in grappling with the same dilemma—though their answers are often complex and nuanced.

Immanuel Kant

Immanuel Kant (1724-1804), often hailed as the 'father of modern ethics,' led a life widely regarded as remarkably mundane. So much so that, as the story goes, his neighbors allegedly synchronized their watches based on the timing of his daily strolls.

Although Kant's work predates Schopenhauer's, he didn't explicitly tackle the question, 'What is the meaning of life?' However, his writings deeply engage with the theme, making his contributions indispensable. Kant would likely have approached the answer in one of two distinct ways.

Kant aimed to establish a moral framework enabling individuals to determine the right course of action in any situation based on the fundamental definition of morality (the essence of the term ought). He believed this approach would ground morality entirely in reason, allowing us to uncover synthetic a priori knowledge—insights gained through pure reasoning rather than experience, revealing previously unknown truths about the world. This led to his formulation of the 'categorical imperative,' detailed in his Groundwork of the Metaphysics of Morals:

 “I ought never to act except in such a way that I could also will that my maxim should become a universal law.”

Kant argued that an action is morally permissible only if its guiding principle, or maxim, could be universally applied without creating contradictions. For instance, lying fails this test: if everyone lied, trust would erode, rendering lying ineffective. While this primarily identifies what to avoid, it carries significant implications: by deeply reflecting on ourselves and the world, we can establish objective moral standards to guide our lives.

Kant’s second potential answer is outlined in his Critique of Pure Reason, where he sought to address ideas proposed by Scottish philosopher David Hume (1711-1776). Kant described the conditions necessary for experience, asserting that knowledge arises from a dual process: “Intuition and concepts form the foundation of all cognition, meaning neither concepts without some form of intuition nor intuition without concepts can produce knowledge. Both can be either pure or empirical.” Essentially, thought combines sensory data (Intuition) with interpretive frameworks (Concepts).

However, Kant believed that neither sensory data nor concepts reach us unfiltered. He proposed that a priori structures shape how we perceive the world, with one such structure being the concept of cause and effect.

When Kant stated, “the pure or universal laws of nature, which, without relying on specific perceptions, contain only the conditions for their necessary connection in experience,” he argued that universal laws like cause and effect are constructs of our minds, enabling us to make sense of the world. By this logic, cause and effect (as well as space and time) may not exist independently of our mental processes. Consequently, life, as an effect, might lack inherent meaning outside the workings of our minds.

Kant ultimately resolves these ideas by invoking God—a philosophical shortcut—but these concepts were further developed and expanded upon by later thinkers.

Friedrich Nietzsche

Friedrich Nietzsche (1844-1900) remains one of the most misinterpreted philosophers, largely due to the alterations made by his sister and literary executor, Elisabeth Förster-Nietzsche, after his passing. According to Britannica, she “edited his works carelessly and without comprehension,” spreading her distorted versions to a broad audience. Despite this, Nietzsche was a profoundly complex thinker whose ideas have left a lasting impact on countless individuals.

Nietzsche dismissed Schopenhauer’s notion that life is governed by a 'will to live,' pointing out that some individuals sacrifice their lives for their aspirations. Instead, he proposed a 'will to power,' where living beings strive to express their strength—essentially, to realize and affirm their distinct potential.

But what defines our individual strength? Nietzsche dismissed Kant’s emphasis on pure reason, instead advocating for psychology as the key to addressing fundamental questions: “For psychology is once more the path to the fundamental problems,” he stated in Beyond Good and Evil. Nietzsche believed that shedding societal, religious, and historical constraints is essential to becoming a 'free spirit'—someone who thinks independently (a true philosopher). Only then can one transcend 'good and evil,' the imposed morality of the world. He explains that we must uncover what lies “at the core of our souls, deep within, something unteachable, a bedrock of spiritual destiny, of predetermined decisions and answers to chosen questions. In every fundamental issue, an immutable 'I am this' speaks; a thinker cannot rediscover man and woman but can only fully understand—only follow to the end what is 'fixed' about them within himself.”

According to Nietzsche, through deep psychological introspection (though he acknowledges this may not always suffice or be entirely accurate), we can uncover our unique purpose—buried beneath layers of societal norms—and strive to realize it at all costs.

Albert Camus

Albert Camus (1913-1960), a French-Algerian philosopher and author of The Stranger, was a prominent figure often linked to existentialism, though he denied this association, sparking ongoing debate about his philosophical stance. His views on life's meaning build upon Kant’s second potential conclusion. Camus observed that humans instinctively seek causes for effects, yet acknowledged that all prior efforts to uncover an objective 'meaning' of life had fallen short. Existentialists refer to this divide—between our desire for explanation and the universe’s inherent indifference—as 'the absurd.'

Camus compared human existence amidst the absurd to the Greek myth of Sisyphus, condemned to eternally push a boulder uphill only to watch it roll back down. Camus’s solution was to embrace life with clarity and defiance. As he stated in his essay “The Myth of Sisyphus,” “One must imagine Sisyphus happy.” By recognizing that meaning is something we create rather than receive, we empower ourselves to find purpose—ultimately enriching our lives.
