No thoughtful man ever came to the end of his life, and had time and a little space of calm from which to look back upon it, who did not know and acknowledge that it was what he had done unselfishly and for others, and nothing else, that satisfied him in the retrospect, and made him feel that he had played the man.
What verse is for the poet, dialectical thinking is for the philosopher. He grasps for it in order to get hold of his own enchantment, in order to perpetuate it.
Every thoughtful, well-meaning and conscientious human being
should assume in time of peace,
the solemn and unconditional obligation
not to participate in any war, for any reason
or to lend support of any kind, whether direct or indirect.

If thinking is like perceiving, it must be either a process in which the soul is acted upon by what is capable of being thought, or a process different from but analogous to that. The thinking part of the soul must therefore be, while impassable, capable of receiving the form of an object; that is, must be potentially identical in character with its object without being the object. Mind must be related to what is thinkable, as sense is to what is sensible.
