For a wrongdoer to be undetected is difficult; and for him to have confidence that his concealment will continue is impossible.

I was not, I was, I am not, I care not. (Non fui, fui, non sum, non curo)

What men fear is not that death is annihilation but that it is not.

He who has peace of mind disturbs neither himself nor another.

The fool, with all his other faults, has this also, he is always getting ready to live.

Death is nothing to us: for that which is dissolved is without sensation; and that which lacks sensation is nothing to us.

If you would enjoy real freedom, you must be the slave of Philosophy.
