So long as a man imagines that he cannot do this or that, so long as he is determined not to do it; and consequently so long as it is impossible to him that he should do it.
Minds, however, are conquered not by arms, but by love and nobility.
Whatsoever is contrary to nature is contrary to reason, and whatsoever is contrary to reason is absurd.
I call him free who is led solely by reason.
It may easily come to pass that a vain man may become proud and imagine himself pleasing to all when he is in reality a universal nuisance.
Only that thing is free which exists by the necessities of its own nature, and is determined in its actions by itself alone.
