384 – 322 BC
The founder of formal logic, Greek philosopher Aristotle (384–322 BC), was also an astounding scientist, who pioneered the study of zoology. Indeed, his scope of intellect ranged from ethics to aesthetics, logic and biology and everything in between. He enrolled in Plato’s Academy when he was 17 and devoted his entire life to study. After Plato’s death, Aristotle went on to be the private tutor to Alexander the Great for at a time, and then, with Alexander’s permission, built his own academy in Lyceum.
At the school, Aristotle was known to lecture while walking about the campus, which gave rise to his students being dubbed, “Peripatetics,” or those who travel from place to place. The school housed one of the most impressive libraries of the ancient world, and offered open and free lectures to the public.
Christian scholasticism and Medieval Islamic philosophy were rooted in Aristotle’s philosophical and scientific systems. He formalized universal principles of logic that used deduction and inference to form logical arguments, his most famous being syllogism.
Despite only 31 of his 200 manuscripts remaining today, Aristotle’s legacy remains immeasurably far-reaching as his arguments touched on almost every aspect of human knowledge, and philosopher’s continue to debate, interpret and teach his principles.
Our first presupposition must be that in nature nothing acts on, or is acted on by, any other thing at random, nor may anything come from anything else, unless we mean that it does so in virtue of a concomitant attribute.
It is plain then that they all in one way or another identify the contraries with the principles. And with good reason. For first principles must not be derived from one another nor from anything else, while everything has to be derived from them. But these conditions are fulfilled by the primary contraries, which are not derived from anything else because they are primary, nor from each other because they are contraries.
To or to Plato the State is, above all, a large and powerful educative agency which gives the individual increased opportunities of self-development and greater capacities for the enjoyment of life.

Even a woman may be good, and also a slave; though the woman may be said to be an inferior being, and the slave quite worthless.
The statement that complete separation never will take place is correct enough, though Anaxagoras is not fully aware of what it means. For affections are indeed inseparable. If then colours and states had entered into the mixture, and if separation took place, there would be a ‘white’ or a ‘healthy’ which was nothing but white or healthy, i. e. was not the predicate of a subject.
