The only real ill-doing is the deprivation of knowledge.

And is it not true that in like manner a leader of the people who, getting control of a docile mob, does not withhold his hand from the shedding of tribal blood, but by the customary unjust accusations brings a citizen into court and assassinates him, blotting out a human life, and with unhallowed tongue and lips that have tasted kindred blood, banishes and slays and hints at the abolition of debts and the partition of lands.

Music gives wings to the mind and flight to the imagination.

Where love reigns, there's no need for laws.

And what shall he suffer who slays him who of all men, as they say, is his own best friend? I mean the suicide, who deprives himself by violence of his appointed share of life. Not because the law of the state requires him. Nor yet under the compulsion of some painful and inevitable misfortune which has come upon him. Nor because he has had to suffer from irremediable and intolerable shame, but who from sloth or want of manliness imposes upon himself an unjust penalty.

It is vain for the sober man to knock at poesy's door.

Wonder is the feeling of the philosopher, and philosophy begins in wonder.
