The First Philosophers (2000) is a collection of the ideas of the most important Greek philosophers that lived before or were contemporaries of Socrates. This somewhat arbitrary distinction between pre-Socratic and post-Socratic philosophy becomes problematic when one reads about the ideas of these thinkers. Socrates, and even more so Plato, cannot be understood without connecting them to their predecessors – theirs was a reaction to developments in (mostly) natural philosophy – explaining the world in natural terms.
That this last step was a major one, we can all agree on. All human cultures need narratives to explain their origins, the origins of the world, the origins of humanity, and all the change and reality that is part of our world. Primitive cultures explain all of this in terms of myths: stories about ancestors from long ago, about heroes and about gods. These archetypical explanations are deemed to be sufficient and when people suffer or need some desire fulfilled, they simply turn to the gods and ancestral heroes, sacrifice something and pray for change.
The significance of the Greek philosophers lies in the fact that they started to look for explanations of the world in natural terms. Thales of Miletus is usually credited as founding father of this tradition – he offered the first rational explanations of natural phenomena in purely worldly terms. Miletus was a trading hub connecting the Greek world with the Babylonian, Egyptian and Indian worlds and hence promoting the intercourse of ideas. One of the Milesians, Anaximander, can up with the first interesting cosmogony: all change is the change of form, while the underlying material that takes on different shapes is one, infinite, indefinite and eternal being. This ultimate matter is fire, which rarefies or condenses and through this mechanism takes on different forms.
Silly as such ideas sound to us modern readers, this is a truly ground-breaking shift in thinking: looking for abstract reality instead of turning to gods.
Heraclitus took these ideas of change and reality to a whole new level. According to him, the world is in a continuous state of flux, but behind this apparent flux lies an unchanging reality. The world is one, everything is fire, and the constant change of fire into its many forms through rarefaction and condensation follows the war-principle: constant strife between generation and degeneration of forms. This led Heraclitus to the important conclusion that to grasp truth, one needs to use his senses to observe the change all around us, and then use his intellect to arrive at the underlying reality. So, when Heraclitus claims “most people are asleep”, what he means is that the road to knowledge requires both sensory experience and intellectual reasoning, something which is not given to many people.
The major pivot in Greek philosophy came with Parmenides, who developed a whole new perspective on knowledge, reality and change – in opposition to the Milesians and Heraclitus. According to Parmenides, using logical reasoning, “everything that is, is.” In other words, Being (what-is) is the foundation of the world (which clearly is). Thus, all theories of change, flux, multiples, etc. are false – they try to look for reality, Being, in appearance. All predecessors, according to Parmenides, were seduced by the human senses: we perceive change, but reason tells us this is impossible. So sensory experience is illusory and reason is the only path to knowledge. Reason tells us that what-is, one substance, is immutable, while our senses deal only with finite qualities or properties of substance.
Parmenides’ radical rationalism, doing away with sensory experience and turning the mind on itself in its quest for Truth, was the foundation of a whole new school of philosophy: the Eleatics. Zeno, part of this school, tried to defend Parmenides’ monism by offering a plethora of logical arguments – for example, arguing that since everything that is, is, nothing what-is, is not; concluding that plurality (i.e. presupposing non-existence) is impossible. He is also known for his famous paradoxes that prove motion is impossible – for example proving that an arrow doesn’t move but only takes on different locations in spacetime. That rationalism can lead to strange conclusions is something the history of philosophy can attest to; Aristotle proved that Zeno’s paradoxes can be dissolved by simply pointing to the fact that Zeno treats time in a (arbitrary) different way than space.
Another Eleatic, Melissus, tried to defend Parmenides’ rationalism on a different ground: since something cannot come from nothing; and change is destruction of what-is; change (i.e. the creation from something new out of nothing) is impossible. Thus, according to Melissus, what-is (i.e. Parmenides’ substance) exists infinitely and absolutely. Since everything material is extended (i.e. measured in magnitudes), no material is substance (i.e. infinite, unextended). With Parmenides, Zeno and Melissus, we see the retreat of the mind into itself, leaving the world of our senses more and more as not interesting in our quest for Truth.
Someone who ended up in this same position, but along totally different lines of thought, was Pythagoras. The Pythagoreans were more a mystic, religious sect than a philosophical school, notwithstanding some important philosophical and scientific discoveries made by them. Also, the historical tradition has greatly distorted their true thoughts and behaviour. In general, the importance of the Pythagoreans for philosophy lies in the facts that (1) they explained nature in terms of arithmetic (i.e. “everything is number”) and (2) they came up with the notion of metempsychosis, or the transmigration of soul.
The Pythagoreans believed souls are immortal and are placed continuously in the bodies of different organisms; according to how well you lived, your soul would either enter a higher or lower organism in the next life. This explains their strange rules of life, for example not eating or harming animals (they could be the new bodies of your deceased relatives’ souls). Finally, the Pythagoreans saw harmony as the relationship between odd and even numbers (as in the length of lyres, musical instruments) and between limited and unlimited numbers. Since the heavenly bodies (stars, planets) can be described in terms of numbers, harmony plays a part here as well, and the planets were even deemed to make harmonious music, just like Earthly instruments, albeit in such a distance from us that we can never hear it. The reduction of diverse, worldly phenomena into the same terms – numbers – is an interesting perspective which would be one of the building blocks of the scientific revolution in the seventeenth century.
So the main line of development is from the Milesians and Heraclitus, to the Eleatics and Pythagoreans. With the establishment of Parmenidean monism and ontology, came new thinkers who reacted to this established system of natural philosophy. So, for example, Anaxagoras claimed that everything in the world contains a portion of everything. In other words, everything in the world is composed of a mix of one all-encompassing soup of materials. The different proportions in this mix determine the character of things. This original mixture was organized by a pure, unmixed Mind, who thus created the cosmos (literally, order). This Mind participates in matter, in different degrees, and this explains the biology of all living creatures.
Another thinker, Empedocles, tried to offer a somewhat more precise system of nature. According to him, there are four roots (or elements) – fire, air, water, earth – and four qualities – hot, dry, wet, cold – which are ordered by two principles – love (attraction) and strife (repulsion). The combination of the four roots, four qualities and two principles, leads to a cyclical cosmos in which then love, then strife, dominates. Life is generated through fire (the burning souls are why living organisms are warm and dead organisms are cold) and follows a cyclical pattern as well. First, there are perfect souls, daimons, and through the eating of meat, the souls degenerate, and the cosmos ends up with human beings.
According to Empedocles, truth cannot be gained by the use of the intellect alone – we need our sense experience. How we arrive at truth is to shut off our intellect associating when we perceive the world: only through deliberate, almost apathic reflection can be perceive the world as it is. When we study the world in this way, we learn that nothing really is destroyed or created out of nothing, so Parmenides’ monism (one indeterminate and infinite substance) seems to be true. Nevertheless, all matter is composed of a mixture of the four indestructible elements, leaving room for multiplicity (contra Parmenides). The principles of love and strife regulate change.
The key thing to note in Anaxagoras and Empedocles is that both explain a dynamic universe in natural terms, without having recourse to mythology. They try to come up with rational explanations, drawn from sense experience and logic.
After Empedocles, the Atomists extended many notions of their predecessors and offered a new system of the world. Atomism is primarily a reaction against Parmenidean monism and its main ideas are: (1) atoms are indivisible constituents of matter, (2) matter is infinite (and thus there are infinite amounts of worlds), (3) void is the space in which matter moves, (4) and thus both what-is (matter) and what-is-not (void) exist. Their stance on the sense experience-reason debate is ambiguous as well: sensory information is uncertain and hence unreliable, while intelligence can grasp Truth – in a sense, this is materialist rationalism.
The Atomists also drew metaphysical conclusions from their materialism: (1) the soul is material (fire particles), (2) the gods are material, (3) particles of destroyed world hit Earth and cause plagues and disease, and (4) happiness is in the mind, leading to an ethics of seeking contentment and overcoming fear. Once again, it is not so much the precise ideas (which might sound silly to us moderns) but the search for natural causes that account for phenomena, for example explaining diseases and plagues in terms of other-worldly particles reaching Earth.
The last of the pre-Socratics, Diogenes, offered a return to Milesian-style philosophy: explaining the cosmos is terms of one, unifying principle – air, in his case. So everything is air, either in more or less, condensed or rarefied form. Bodies contain air, the heart pumps it through our bodies via the bloodstream and sperm contains air that generates new life through procreation. The interesting idea here is that Diogenes, himself a doctor, uses human anatomy to explain certain natural phenomena (bodily warmth, reproduction, etc.) and looks for an underlying, unifying natural case (air). This is a significant change from earlier mythological narratives!
In sum: all these thinkers (the Milesians, the Eleatics, the Pythagoreans, Anaxagoras, Empedocles, the Atomists) busied themselves with questions about (1) reality, (2) change and (3) knowledge. And all tried to answer these questions – how silly these answers might seem to us – in terms of underlying unifying principles, natural phenomena and using either reason, sense experience or a combination of both. Socrates, but even more so Plato, build on this framework and took over many established notions – for example Plato’s theory of Forms and his metempsychosis.
But there is of course another trend visible through the history of the Presocratics. Greek culture was a mythological culture – gods, rituals, sacrifices and religious customs were important. By making gods and heroes irrelevant, or even hostile, to natural explanations, the diffusion of natural philosophy was more and more deemed to be a danger to established culture. If all various explanations could be true, and if gods weren’t necessary anymore, then what was left but scepticism and relativism?
The second part of the book deals primarily with the Sophists who seized on these uncertainties and used logical arguments to defend any position they wanted – or were paid for. It would be a mistake, though, to see these people as hirelings or rhetoricians. What they basically occupied themselves with was teaching virtue through rhetoric, built on philosophical principles. During the fifth century B.C., when the Sophists were highly influential, they mainly occupied themselves with two questions: (1) the origin of mankind and society, and (2) the values of law and nature.
In general, they all were moral relativists, in the sense that they saw morality as a convention, either naturally or politically. Most were adherents of democracy and agnosticism (in terms of religion); some tried to establish free education.
Protagoras was mainly known for his moral relativism, seeing morality as a convention; his plea for democracy and free education; and his religious agnosticism. Gorgias saw rhetoric as a neutral tool, to be used for good or bad, depending on the user (comparable to the instrumentalism of modern-day science!) and used rhetoric mainly for moral persuasion. He is also known for his scepticism: (1) nothing exists (since it either is infinite or created – infinity precludes creation, while creation is impossible); (2) even if things existed, they could not be comprehended by us (since the objects of our thoughts are not identical with the objects as they are); (3) even if things existed and could be comprehended, they could not be communicated (since language is not identical with the substance it purports to deal with). In other words: Gorgias distinguishes between appearance and existence – something that would have a fruitful future in philosophy.
Another Sophist, Prodicus, is usually hailed as an important reformer – he tried to establish consensus about the meaning of words in order to be communicate clearly and distinctly. He is also known for his denial of the possibility of contradiction – which usually is used as a criterion of truth. Words either mean something (by convention) or they don’t. Truth, in this conception, is mere resemblance of the word to the substance or property it describes, according to convention.
Hippias and Antiphon are commonly known as subjugators of morality. Hippias claimed man-made law is unjust, since only nature can prescribe law. In other words: when someone transgresses a man-made law, he could always appeal to the unwritten, natural law to overrule the validity of the man-made law. So when society proscribes me not stealing property from someone else, natural law (for example survival when I’m poor and hungry) overrules this man-made law: I can steal and defend myself by appealing to my poverty and hunger.
Antiphon takes this argument to a whole new level by claiming natural law is the only just law and that one should follow man-made law as long as this is necessary and can’t be avoided – in all other circumstances one should follow the (unbreakable) natural law. So, according to Antiphon, we should be moral hypocrites out of self-interest.
Another Sophist, Trasymachus, follows Hippias’ stance on natural law, but offers his own ethical guidelines: just is the advantage of the stronger party (ethical nihilism à la Nietzsche) or just is someone else’s good (natural rights) – so we should strive to be unjust, based on self-interest.
We see in the Sophists – especially Hippias, Antiphon and Trasymachus – a trend in fifth century Greece: conventional morality was under attack. Scepticism led to atheism and agnosticism; moral relativism led to the uncovering of the current morality as a tool by the rulers to keep everyone quiet and in their social stations. The preaching of moral hypocrisy, self-interest or outright injustice is, in this narrow sense, a reaction to oppression. Rhetoric was used as a tool to make people aware of all the pitfalls in long-established Greek morality and mythology.
In all, the fifth century Sophists should be seen in the light of the alternative worldviews and ethical approaches offered by the sixth and fifth century Presocratics. The possibility of explaining the world in non-traditional/mythological ways opened up the road to the possibility of coming to new philosophical and moral standards. The problem with moral relativism and scepticism is, though, that this leads either to hopeless aporia’s (in the sense in which Plato’s dialogues so beautifully portray – the only thing I know is that I know nothing) or to self-defeating criticism. If everything is unknowable, the proposition itself is unknowable, but that would mean that there is something that is knowable…
Anyway, The First Philosophers is a very remarkable collection of important material, illustrating the most important natural philosophers and rhetoricians that came prior to Socrates, Plato and Aristotle. It is an important book in that it teaches us that Plato didn’t pop out of a vacuum: most of his ideas (including the ideas of Socrates) can be traced back to earlier forms, and some ideas are literally taken over. It is a healthy illustration of Isaac Newton’s phrase “standing on the shoulders of giants.”
The book itself is highly readable, contains a superb introduction and it offers clear and illuminating remarks about the material of all the different philosophers. For one, it is extremely critical of the conclusions drawn by later philosophers, who distorted, misrepresented or misunderstood the original thinkers. The book also shows how little we know from original sources and how much we rely on second-hand or even more indirect sources – with all the pitfall this brings. A very nuanced, accessible and enlightening book – truly worth a recommendation!
