For what purpose humanity is there should not even concern us: why you are here, that you should ask yourself: and if you have no ready answer, then set for yourself goals, high and noble goals, and perish in pursuit of them!
He who would reach the desired goal must, while a boy, suffer and labor much and bear both heat and cold.
[Lat., Qui studet optatam cursu coningere metam
Multa tulit fecitque puer, sudavit et alsit.]
Each man lives for himself, uses his freedom to achieve his personal goals, and feels with his whole being that right now he can or cannot do such-and-such an action; but as soon as he does it, this action, committed at a certain moment in time, becomes irreversible, and makes itself the property of history, in which is has not a free but a predestined significance.
Nonviolence is the only way. Even if you achieve your goal by violent means there are always side effects, and these can be worse than the problem. Violence is against human nature.
