Aristotle (384–322 BC) was an ancient Greek philosopher and scientist. His writings cover many subjects including physics, metaphysics, biology, zoology, meteorology, geology, economics, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, logic, linguistics, politics and government.
At 17 or 18 years of age, Aristotle joined Plato's Academy. In 338 BC, he began tutoring Alexander the Great. In 335 BC, Aristotle founded his own school, the Lyceum, in Athens. Along with Plato, he is considered the "Father of Western Philosophy".
Knowing yourself is the beginning of all wisdom. Happiness is the meaning and the purpose of life, the whole aim and end of human existence. It is the mark of an educated mind to be able to entertain a thought without accepting it. Educating the mind without educating the heart is no education at all. No great mind has ever existed without a touch of madness. Quality is not an act, it is a habit. Happiness depends upon ourselves. Hope is a waking dream.
Anybody can become angry — that is easy, but to be angry with the right person and to the right degree and at the right time and for the right purpose, and in the right way — that is not within everybody's power and is not easy.
Aristotle You will never do anything in this world without courage. It is the greatest quality of the mind next to honor. What is a friend? A single soul dwelling in two bodies. Excellence is never an accident. It is always the result of high intention, sincere effort, and intelligent execution; it represents the wise choice of many alternatives - choice, not chance, determines your destiny. Well begun is half done. One swallow does not make a summer, neither does one fine day; similarly one day or brief time of happiness does not make a person entirely happy. The high-minded man must care more for the truth than for what people think. Be a free thinker and don't accept everything you hear as truth. Be critical and evaluate what you believe in. Wishing to be friends is quick work, but friendship is a slow ripening fruit. Those who know, do. Those that understand, teach. Pleasure in the job puts perfection in the work. For the things we have to learn before we can do them, we learn by doing them. A friend to all is a friend to none. Learning is not child’s play; we cannot learn without pain. Time crumbles things; everything grows old under the power of time and is forgotten through the lapse of time. Dignity does not consist in possessing honors, but in the consciousness that we deserve them. Patience is bitter, but its fruit is sweet. The law is reason, free from passion. Those who educate children well are more to be honored than they who produce them; for these only gave them life, those the art of living well. The aim of art is to represent not the outward appearance of things, but their inward significance. I count him braver who overcomes his desires than him who conquers his enemies; for the hardest victory is over self. To perceive is to suffer.
The wise man does not expose himself needlessly to danger, since there are few things for which he cares sufficiently; but he is willing, in great crises, to give even his life – knowing that under certain conditions it is not worthwhile to live.
Aristotle He who has overcome his fears will truly be free. Misfortune shows those who are not really friends. It is easy to perform a good action, but not easy to acquire a settled habit of performing such actions. The educated differ from the uneducated as much as the living differ from the dead. Whatever lies within our power to do lies also within our power not to do. Whosoever is delighted in solitude, is either a wild beast or a god. He who cannot be a good follower cannot be a good leader. Poverty is the parent of revolution and crime. Fear is pain arising from the anticipation of evil. It is not enough to win a war; it is more important to organize the peace. It is of the nature of desire not to be satisfied, and most men live only for the gratification of it. The antidote for fifty enemies is one friend. The energy of the mind is the essence of life. To write well, express yourself like the common people, but think like a wise man. At his best, man is the noblest of all animals; separated from law and justice he is the worst. The worst form of inequality is to try to make unequal things equal. The whole is greater than the sum of its parts. He who is unable to live in society, or who has no need because he is sufficient for himself, must be either a beast or a god. It is not always the same thing to be a good man and a good citizen. All human actions have one or more of these seven causes: chance, nature, compulsion, habit, reason, passion, and desire. Democracy is when the indigent, and not the men of property, are the rulers. The more you know, the more you know you don't know. Without friends, no one would want to live, even if he had all other goods. Good habits formed at youth make all the difference. Wit is educated insolence. The state comes into existence for the sake of life and continues to exist for the sake of good life. I have gained this by philosophy … I do without being ordered what some are constrained to do by their fear of the law.
It is just that we should be grateful, not only to those with whose views we may agree, but also to those who have expressed more superficial views; for these also contributed something, by developing before us the powers of thought.
Aristotle All men by nature desire to know. Education is an ornament in prosperity and a refuge in adversity. Nature does nothing uselessly. Personal beauty is a greater recommendation than any letter of reference. Youth is easily deceived because it is quick to hope. In a democracy the poor will have more power than the rich, because there are more of them, and the will of the majority is supreme. To run away from trouble is a form of cowardice and, while it is true that the suicide braves death, he does it not for some noble object but to escape some ill. The soul never thinks without a picture. It is our choice of good or evil that determines our character, not our opinion about good or evil. All persons ought to endeavor to follow what is right, and not what is established. Character may almost be called the most effective means of persuasion.
