This has been the most lucid and concise book on Greek philosophy that I have so far read. In a short 168 pages, the essence of the pre-Socratic and post eras of Greek thought is revealed in both as a refresher from other sources and in additional clarifying points. Definitely beneficial in gaining the grasp of ancient Greek thought.

Guthrie starts out explaining the division of philosophers into the materialists or matter philosophers and the teleologists or form philosophers. The Ionian or Milesian School attempted at a scientific explanation represented by Thales, Anaximander and Anaximenes. It was Thales who taught that the world was made from water and moisture, while Anaximander saw it as a warring of many opposites, and unlike Pythagoreans – of no distinctions, no limitations, the earth as a sphere resting on nothing. And Anaximenes.taught the primary substance of the world was air. All had various ideas on explaining movement.

The Pythagoreans came from an Italian school, as opposed to the Ionian, and was a religious brotherhood defining reality as a combination of substances in a harmonious blend based on mathematics, and discovered the mathematics to musical arrangement. The believed in the immortality and transmigration of the soul, the kinship with nature, the earth as an organism, a kind of pantheism. So it was the limit put on the limitless that arranged and harmonized nature by numerical system, a ruling principle, the meaning of the good – a state of harmonia.

The next philosopher in succession was Heraclitus who criticized the others in their search for facts, teaching that the substance of the world was never a still fact, but was fire, that everything must be destroyed to be born, that all things are in constant motion, in flux, rejecting the peaceful and harmonious world of opposites taught by the Pythagoreans. Nothing was constant, universal and eternal, all was in constant temporal states.

Parmenides taught the opposite, in that movement was impossible, for there was no such thing as empty space, and the whole of reality consisted of a single, motionless and unchanging substance. Such reality was non-sensible, only to be reached by thought.

The pluralists consisted of Empedocles, Anaxogoras and Democritus. Empedocles taught similar to the Pythagoreans that the world was a variety of harmonious combinations of the four root substances of earth, water, air and fire. He also included the ingredients of love and strife in a materialistic way. Anaxogoras, using a atomic theory, believed in a moving cause apart from the matter into a collective mind which rules the world, a mind behind the universe which governs and orders its changes. The atomic theory was fully attributed to Democritus and possibly Leucippusa. The atomic view had the problem of movement which needed empty space. While later Epicurus took up gravity as a reason, it was a retrograde step and Democritius was thinking more clearly when he saw that in infinite space the conception of up or down had no meaning.

Next comes the sophists and it was Protagoras that taught pragmatism, that while there is no opinion that is truer, there are those that can be better, better in the sense of the individual in unifying harmony with the majority or collective. However, the sophists endorsed a severe relativity and values became choices of multiple word definitions chosen to each particular argument. Right and wrong, wisdom, and justice and goodness became nothing but names. And so it was Socrates that came up with a method to acquire arete, efficiency and excellence in the trade or occupation one does.This method consisted of inductive argument and general definition, that is exposing the false definitions and replacing them with the common meaning to the particular word or value. It was then that not an absolute was established, but rather an a higher level of reasoning in a continuous, advanced inquiry.

Plato, speaking of Socrates, took the ever moving flux of Heraclitus and the ever still unchanging world of Parmenides into a two world system, the world of the senses and the world of eternal ideas or forms. Thus individualism could be curbed and collective agreement could be established for the survival of the polis or city-state. He also incorporates the ideas of Pythagoreans’ immortality and transmigration of the soul and the process of recollection. He taught dialectical thinking but beyond that used myth to provide for regions beyond such explanations. Virtue or efficiency and excellence is knowledge, knowledge needed to fully excel.

Guthrie next goes into an explanation of the Republic and government with the three parts of an individual and three classes of people and then into the Laws. The classes consisted of the ruling party and the soldier party, both with censorship and undemocratic authority but not able to own private property and of a poorer nature. Those that ruled did so out of a service, not out of a luxury or desires. It was the masses or working class that obeyed but the only ones who had the ability to gain riches.

Aristotle is then described in his rejection of the Platonic world of ideas and his idea of the universe, relying on the mental process or reason, common principles, the idea of immanent form and the conception of potentiality applying that to the problem of motion. He arrived at the concept of God as the Unmoved Mover, motionless, yet caused movement from actuality from engagement of eternal thought activity of the pure mind, which is life. This then brought motion and potentiality. More is mentioned on ethics, classes of the good by habits, man being a political animal is the answer over the world of ideas, and paradoxically states that divine reason can not be fully attained by man and yet it is foolish to emulate the gods and poets, but man should aim at his fullest potentiality. The ergon of every creature is to attain its own forma and perform its proper activity. The activity of mind is life.
