Aristotle
Aristotle was a Greek philosopher and scientist born in the city of Stagira, Chalkidice, on the northern periphery of Classical Greece. His father, Nicomachus, died when Aristotle was a child, whereafter Proxenus of Atarneus became his guardian. At eighteen, he joined Plato's Academy in Athens and remained there until the age of thirty-seven. His writings cover many subjects – including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theater, music, rhetoric, linguistics, politics and government – and constitute the first comprehensive system...

Truth is a remarkable thing. We cannot miss knowing some of it. But we cannot know it entirely.
We do not know a truth without knowing its cause.
Knowing what is right does not make a sagacious man.
For knowing is spoken of in three ways: it may be either universal knowledge or knowledge proper to the matter in hand or actualising such knowledge; consequently three kinds of error also are possible.
Actual knowledge is identical with its object: in the individual, potential knowledge is in time prior to actual knowledge, but in the universe as a whole it is not prior even in time. Mind is not at one time knowing and at another not. When mind is set free from its present conditions it appears as just what it is and nothing more: this alone is immortal and eternal (we do not, however, remember its former activity because, while mind in this sense is impassible, mind as passive is destructible), and without it nothing thinks.
The physician himself, if sick, actually calls in another physician, knowing that he cannot reason correctly if required to judge his own condition while suffering.
Wealth comes from knowing what others do not know.
It is possible to fail in many ways...while to succeed is possible only in one way.
It is easy to fly into a passion - anybody can do that - but to be angry with the right person to the right extent and at the right time with the right object and in the right way - that is not easy, and it is not everyone who can do it
Melancholy men are of all others the most witty.
Wicked men obey from fear; good men, from love.
To the query, ''What is a friend?'' his reply was ''A single soul dwelling in two bodies.''
To write well, express yourself like common people, but think like a wise man. Or, think as wise men do, but speak as the common people do.
The greatest of all pleasures is the pleasure of learning.
