“Your worst sin is that you have destroyed and betrayed yourself for nothing.”
― Fyodor Dostoevsky, Crime and Punishment

“Hence a young man is not a proper hearer of lectures on political science; for he is inexperienced in the actions that occur in life, but its discussions start from these and are about these; and, further, since he tends to follow his passions, his study will be vain and unprofitable, because the end aimed at is not knowledge but action. And it makes no difference whether he is young in years or youthful in character; the defect does not depend on time, but on his living, and pursuing each successive object, as passion directs. For to such persons, as to the incontinent, knowledge brings no profit; but to those who desire and act in accordance with a rational principle knowledge about such matters will be of great benefit.”
― Aristotle, The Nicomachean Ethics

“A society grows great when old men plant trees in whose shade they shall never sit.”

“The tree of Liberty must be refreshed from time to time with the blood of patriots and tyrants.”
