As the body is mortal and is subject to physical death, the soul must be its indestructible opposite. Plato then suggests the analogy of fire and cold. If the form of cold is imperishable, and fire, its opposite, was within close proximity, it would have to withdraw intact as does the soul during death. The Argument from Opposites absorbs a line of thinking that was popular among earlier philosophers such as Heraclitus and Pythagoras. By following their lead in seeing the world as being divided into opposites, Plato presents an initial argument that would be sympathetic to his contemporaries.

True knowledge, argues Socrates, is knowledge of the eternal and unchanging Forms that underlie perceptible reality. For example, we are able to perceive that two sticks are equal in length but unequal in width only because we have an innate understanding of the Form of Equality.

That is, we have an innate understanding of what it means for something to be equal even though no two things we encounter in experience are themselves perfectly equal. Since we can grasp this Form of Equality even though we never encounter it in experience, this argument implies that the soul must have existed prior to birth. The Theory of Recollection introduces the idea of Forms and, in associating knowledge with the immortal soul, suggests that the soul that survives death is not just an empty life force but includes the intellect.


He particularly mentions the Egyptian mathematicianswhose knowledge he praises. Theophrastustoo, spoke of him as a man who had seen many countries. He traveled throughout Greece to acquire a better knowledge of its cultures. He mentions many Greek philosophers in his writings, and his wealth enabled him to purchase their writings.

Leucippusthe founder of atomismwas the greatest influence upon him.

He also praises Anaxagoras. One story has him deliberately blinding himself in order to be less disturbed in his pursuits; [23] it may well be true that he lost his sight in old age. He was cheerful, and was always ready to see the comical side of life, which later writers took to mean that he always laughed at the foolishness of people. Most sources say that Democritus followed in the tradition of Leucippus and that they carried on the scientific rationalist philosophy associated with Miletus.

Both were thoroughly materialistbelieving everything to be the result of natural laws. Unlike Aristotle or Plato, the atomists attempted to explain the world without reasoning as to purpose, prime moveror final cause. For the atomists questions of physics should be answered with a mechanistic explanation "What earlier circumstances caused this event? Aesthetics Later Greek historians consider Democritus to have established aesthetics as a subject of investigation and study, [29] as he wrote theoretically on poetry and fine art long before authors such as Aristotle.

Specifically, Thrasyllus identified six works in the philosopher's oeuvre which had belonged to aesthetics as a discipline, but only fragments of the relevant works are extant; hence of all Democritus's writings on these matters, only a small percentage of his thoughts and ideas can be known.

Atomic hypothesis See also: Atomism The theory of Democritus held that everything is composed of "atoms", which are physically, but not geometrically, indivisible; that between atoms, there lies empty space; that atoms are indestructible, and have always been and always will be in motion; that there is an infinite number of atoms and of kinds of atoms, which differ in shape and size. Of the mass of atoms, Democritus said, "The more any indivisible exceeds, the heavier it is".

But his exact position on atomic weight is disputed. They reasoned that the solidness of the material corresponded to the shape of the atoms involved. Thus, iron atoms are solid and strong with hooks that lock them into a solid; water atoms are smooth and slippery; salt atoms, because of their taste, are sharp and pointed; and air atoms are light and whirling, pervading all other materials.

Moreover, connections were explained by material links in which single atoms were supplied with attachments: In contrast, modern, quantum-mechanical atoms interact via electric and magnetic force fields and are far from inert.

The theory of the atomists appears to be more nearly aligned with that of modern science than any other theory of antiquity. However, the similarity with modern concepts of science can be confusing when trying to understand where the hypothesis came from. Classical atomists could not have had an empirical basis for modern concepts of atoms and molecules. However, Lucretiusdescribing atomism in his De rerum naturagives very clear and compelling empirical arguments for the original atomist theory.

He observes that any material is subject to irreversible decay. Through time, even hard rocks are slowly worn down by drops of water. Things have the tendency to get mixed up: Mix water with soil and mud will result, seldom disintegrating by itself.

However, there are mechanisms in nature and technology to recreate "pure" materials like water, air, and metals. The conclusion is that many properties of materials must derive from something inside, that will itself never decay, something that stores for eternity the same inherent, indivisible properties.

The basic question is: Why has everything in the world not yet decayed, and how can exactly some of the same materials, plants, and animals be recreated again and again? One obvious solution to explain how indivisible properties can be conveyed in a way not easily visible to human senses, is to hypothesize the existence of "atoms". These classical "atoms" are nearer to humans' modern concept of "molecule" than to the atoms of modern science. The other central point of classical atomism is that there must be considerable open space between these "atoms": Lucretius gives reasonable arguments[ citation needed ] that the void is absolutely necessary to explain how gasses and liquids can flow and change shape, while metals can be molded without their basic material properties changing.

They held that any movement would require a void—which is nothing—but a nothing cannot exist. The Parmenidean position was "You say there is a void; therefore the void is not nothing; therefore there is not the void".

The atomists agreed that motion required a void, but simply ignored the argument of Parmenides on the grounds that motion was an observable fact.

Therefore, they asserted, there must be a void. This idea survived in a refined version as Newton's theory of absolute spacewhich met the logical requirements of attributing reality to not-being. Einstein's theory of relativity provided a new answer to Parmenides and Zeno, with the insight that space by itself is relative and cannot be separated from time as part of a generally curved space-time manifold.

Consequently, Newton's refinement is now considered superfluous. The knowledge of truth, according to Democritus, is difficult, since the perception through the senses is subjective.
