If there is some end of the things we do, which we desire for its own sake, clearly this must be the good. Will not knowledge of it, then, have a great influence on life? Shall we not, like archers who have a mark to aim at, be more likely to hit upon what we should? If so, we must try, in outline at least, to determine what it is. (I.1094a18)
I grow old ever learning many things.
If you consider what are called the virtues in mankind, you will find their growth is assisted by education and cultivation.
Trees, though they are cut and lopped, grow up again quickly, but if men are destroyed, it is not easy to get them again.
Reason is immortal, all else mortal.
He is the better equipped for life. As for swimming, who has the less to carry.
All is flux, nothing stays still.
To find yourself, think for yourself.
A man may learn wisdom even from a foe.
With regard to excellence, it is not enough to know, but we must try to have and use it.
No law or ordinance is mightier than understanding.
You are providing for your disciples a show of wisdom without the reality. For, acquiring by your means much information unaided by instruction, they will appear to possess much knowledge, while, in fact, they will, for the most part, know nothing at all; and, moreover, be disagreeable people to deal with, as having become wise in their own conceit, instead of truly wise.
The whole is more than the sum of its parts.
Living well and beautifully and justly are all one thing.
But, my dearest Agathon, it is truth which you cannot contradict; you can without any difficulty contradict Socrates.
in Symposium Plato
Partying is such sweet sorrow.
Man is the measure of all things.
The absolute pacifist is a bad citizen; times come when force must be used to uphold right, justice and ideals.
Alfred North Whitehead
A friend is somebody you want to be around when you feel like being by yourself.
He who has hope has everything.
He that has acquired learning and nor practised what he has learnt, is like a man who ploughs but sows no seed.
My passionate sense of social justice and social responsibility has always contrasted oddly with my pronounced lack of need for direct contact with other human beings and human communities. I am truly a "lone traveler" and have never belonged to my country, my home, my friends, or even my immediate family, with my whole heart; in the face of all these ties, I have never lost a sense of distance and a need for solitude - feelings which increase with the years.
Everything we call real is made of things that cannot be regarded as real.
Niels Henrik David Bohr
Without music life would be a mistake.
Friedrich Wilhelm Nietzsche
We hate the very idea that our own ideas may be mistaken, so we cling dogmatically to our conjectures.
Sir Karl Popper
At the time and in the country in which the present study was written, it was granted by everyone except backward people that the Jewish faith had not been refuted by science or by history.... [O]ne could grant to science and history everything they seem to teach regarding the age of the world, the origin of man, the impossibility of miracles, the impossibility of the immortality of the soul, and of the resurrection of the body, the Jahvist, the Elohist, the third Isaah, and so on, without abandoning one iota of the substance of the Jewish faith.
