Life Is Simple: How Occam's Razor Set Science Free and Shapes the Universe

do you make an object on the surface of a rotating sphere wander? The greatest philosopher of the ancient world thought he knew the answer. Plato was born around 428 BCE to a wealthy Athenian family. He became a pupil of Socrates and, after the elder philosopher’s execution, founded the

one that was to profoundly shape the course of Western culture, was his concept of Formsv and the accompanying philosophical tradition known as philosophical realism. Plato’s realism encompasses all aspects of experience but is most easily explained by considering the nature of mathematical and geometrical objects such as circles. He

asked the question, what is a circle? You might indicate a particular example etched into stone or drawn in the sand, but Plato would point out that, if you looked closely enough, you would see that neither it, nor indeed any physical circle, was perfect. They all possessed

have no trouble in recognising and talking about them. So what are we comparing them against to identify them as circles, rocks, fish or cats? Plato’s extraordinary answer was that the world we see is a pale reflection of a deeper reality of Forms, or universals, where perfect cats chase

perfect mice in perfect circles around perfect rocks watched over by perfect nobles. Plato believed that the Forms or universals are the true reality that exists in an invisible but perfect realm beyond our senses. His system is often

known as philosophical realism to denote that Plato, and his followers, believed that Forms or universals are not only real but are the ultimate reality that give rise to our sensory perceptions.vi

Plato graphically illustrated his model in his famous Allegory of the Cave in which he compared the human experience to that of people chained facing the

That this claim was plainly contradicted by his senses must, Plato insisted, be a consequence of the inferior vantage point available to humanity from within the terrestrial cave of our senses. He urged his followers to

pupil, Eudoxus of Cnidus (410–347 BCE) who, in a pattern that will become familiar, added more spheres. Imagine you are standing in Plato’s cave, which lies at the centre of a simplified version of Eudoxus’s model consisting of just a single sphere, which we will represent in Figure

the sky. FIGURE 5: View of the planetary motions in Eudoxus’s model. Eudoxus’s model worked well enough but it needed twenty-seven spheres. Plato’s mechanically minded pupil Aristotle added more spheres to act rather like modern ball-bearings to prevent motion from one sphere being transmitted to adjacent

First, he shifted the earth (Plato’s cave in the figure) from the precise centre of the sphere’s rotations to a point, just off-centre, which was called the eccentric. He also

From a scientific perspective, Aristotle’s universals were a slight improvement on Plato’s Forms since they were considered to exist in the world rather than in some invisible realm. Yet this created a problem: how do we

The basic structure is often illustrated with reference to Plato’s famous teacher: Socrates is a man, all men are mortal, so Socrates is mortal. The logic is founded on the principle that all objects

universals such as ‘manness’ or mortality. Yet, if the only thing in common between Socrates and, say, Plato is a mere word, man, then the fact that Socrates is mortal says nothing about whether Plato or any other man is mortal. The scholastics were horrified. How can they then gain knowledge of

He became enamoured with Plato’s philosophy and particularly his extensive writings on the nature of the soul, which he saw as a means

Sometime between 1469 and 1474, he put together a commentary and summary of Plato’s ideas under the title Theologia Platonica (Platonic Theology) with the provocative subtitle On the Immortality of Souls. Ficino insisted that

Plato, rather than Aristotle, was Christianity’s patron philosopher. Ficino’s translations and commentaries were enormously popular as Plato’s lucid and poetic writing style, filled with allegories, narrative and dialogues, were a welcome release

from the clunky logic of Aristotle. What particularly attracted the humanists was Plato’s focus on self-discovery. The shift from Aristotle’s empiricism to Platonic introspection resonated with the prevailing humanism and sparked a revival of mystical

. When Cosimo de’ Medici heard that some re-discovered Neoplatonist Greek texts had recently arrived in Florence he ordered Ficino to abandon further translations of Plato to focus instead on translating ancient writings by a legendary character known as Hermes Trismegistus, reputed to be an ancient Egyptian ‘thrice great priest, prophet

quest for knowledge is endemic to Greek thought. It is a tragedy shot through with hope. Plato’s allegory of the cave is the most famous example of striving to reach the light. In that allegory, Plato paints a picture of men chained to a wall in a cave, prevented from seeing the source

truth.7 Utilizing human reason to escape the cave, and bringing knowledge of the light, that was the task of ancient Athens—a task uniting Plato (428–348 BCE) and Aristotle (384–322 BCE). The ancient Greeks gave us three foundational principles: first, that we could discover our purpose in life

conclusion of many modern philosophers. It was also the conclusion of certain ancient Greeks like Democritus (460–370 BCE), a philosopher who lived contemporaneously with Plato and Aristotle and believed that all of human life could be boiled down to fundamental particles of matter he called “atoms.”8 Nature was merely

nature; ethics takes a backseat. Plato, Aristotle, and the Stoics thought differently. Plato and Aristotle rejected Democritus’s atomic theory. In their view, the human mind was freely capable of deciphering nature’s rules—and

make him a man, not an animal—man has a telos, too. What is our telos? Our end, according to both Plato and Aristotle, is to reason, judge, and deliberate. Plato put it this way in The Republic: Is there some work of a soul that you couldn’t ever accomplish with

is the use of reason: “the work of a human being is an activity of soul in accord with reason.”11 So, according to both Plato and Aristotle, what makes us “virtuous” is doing our job: look at the world with our reason, discerning the final causes for which things exist

the supposedly perfect harmony of the cosmos. And that led him to the Pythagorean theorem, among other discoveries.15 Plato and Aristotle both believed in the notion of objective truth as well. But Plato and Aristotle disagreed with regard to what constituted objective truth: the Forms, or knowledge of the physical world

GOVERNMENT Finally, the Greeks gave us the roots of democracy. Based on the notion of virtue—use of reason to act in accordance with nature—Plato, Aristotle, and the Stoics developed ethical systems. Those ethical systems didn’t merely recommend personal cultivation. They also encompassed the creation of new forms of

points out, the Athenians universally believed that good citizenship was a prerequisite to being a good man.16 Plato’s ethical system tied together happiness and virtue: the truly virtuous man will be happy. Plato defined various virtues, too: justice, moderation, and the like. But these virtues aren’t individual virtues, in

Plato’s view—they only exist in the context of a community. The virtue of justice, for example, exists when

because cultivating virtue is the ultimate goal of man—the polis must be governed rigorously so that human beings are inculcated with virtue, according to Plato. That means that those who govern must be the best and wisest among us—that we must rigorously condition a class of philosophers to rule

. Otherwise, chaos will ensue. “Unless,” wrote Plato in the voice of Socrates, “the philosophers rule as kings or those now called kings and chiefs genuinely and adequately philosophize, and political power and

for the cities, my dear Glaucon, nor I think for human kind . . . in no other city would there be private or public happiness.”18 In Plato’s view, conflict within the state lies in failure of people to recognize their own station. To solve such conflicts

, Plato set up a rigorous hierarchy in his utopian vision, between workers, warriors, and philosopher kings. He also recommended a communistic vision of his ideal state

in which the philosopher kings are raised. This led philosopher Karl Popper to protest that Plato’s ideal state was “purely totalitarian and anti-humanitarian,” and accuse Plato of re-enshrining “class rule and class privilege . . . the principle that every class should attend to its own business

is just if the ruler rules, if the worker works, and if the slave slaves.”19 In defense, Plato scholars Leo Strauss and Allan Bloom rejected Popper’s critique by suggesting that Plato’s entire scheme was at least partially facetious, an attempt to prove the unworkability of full communitarian control.20

Aristotle’s system of virtue also involved one’s status as a citizen. But unlike Plato, who believed that the Forms could be understood by a select few who could then rule benevolently over the rest of a well-organized society

, Aristotle rejected such utopianism. He tore into Plato’s suggested regime, calling it unrealistic and stating that it would rend apart the society itself. “Let us remember,” Aristotle says, “that we should not

The logic of both Plato and Aristotle tied together the existence of the state to its ability to forward and abide by natural law. Their philosophical heirs, like Cicero, would

Plato, Aristotle, and the Stoics would have all rejected such a division as counterproductive and fruitless: individual purpose lay in acting virtuously—fulfilling our telos by

Uncovering natural law meant seeking to know nature, and Plato, Aristotle, and the Stoics were united in their belief that human beings could turn their minds to nature in pursuit of answers. Humans were graced

Freedom in the modern notion is explicitly rejected by Plato, who felt it would lead to anarchy; according to Aristotle, freedom only exists in the individual context when you are involved in philosophical pursuits.24

communal capacity? The community was tasked with two separate functions: instilling virtue in the citizenry, and protecting the citizens from the violation of natural law. Plato thought that fulfillment of the first function could prevent the necessity for the second: if the government could train perfect philosopher-kings to govern, there

an active God in the universe, Greek thought posited an Unmoved Mover largely unconcerned with human affairs. “The changeless, Unmoved Mover was the God of Plato and Aristotle,” Rabbi Jonathan Sacks says. “The God of history was the God of Abraham. They simply did not belong together.” Judaism believed, as Greek

,” to enact His commandments and, by doing so, spread those universal truths. Universalism suggests that human logic leads to the light outside the cave; particularism suggests that God’s hand can be found in His guidance of one particular nation. Third, Greek commitment to the polis contradicted Jewish commitment to the divine

Jewish law could be abandoned in favor of universalism. As historian Richard Tarnas writes, “That supreme Light, the true source of reality shining forth outside Plato’s cave of shadows, was now recognized as the light of Christ. As Clement of Alexandria announced, ‘By the Logos, the whole world is now become Athens

Aristotle, Cicero, Locke, Sidney, etc.”28 John Adams, the chief congressional sponsor of the Declaration, mirrored Jefferson’s language exactly: “the principles of Aristotle and Plato, of Livy and Cicero, and Sidney, Harrington, and Locke; the principles of nature and eternal reason; the principles on which the whole government over us

existence itself. What did this mean practically? It meant mostly deconstructing ancient notions of eternal truths and human reason going all the way back to Plato and Aristotle. What would fill the gap? Authenticity—the true self, contemplating its own death and the meaninglessness of the universe, “taking hold of itself

a form of wish fulfillment, behavior was a manifestation of unconscious desires; in general, people were governed by forces beyond their control. Mirroring Plato, Freud posited a tripartite soul—Plato suggested reason, spirit, and appetite, while Freud suggested superego (moral reason), ego (life experience militating between appetite and reason), and id (appetite

). But where Plato suggested that man should work to ally spirit with reason to overcome appetite, Freud suggested that working to uncover unconscious forces shaping our id would
