Things that have a common quality ever quickly seek their kind.

Nothing happens to any man which he is not formed by nature to bear. The same things happen to another, and either because he does not see that they have happened or because he would show a great spirit he is firm and remains unharmed. It is a shame then that ignorance and conceit should be stronger than wisdom.

...the sole thing of which any man can be deprived is the present; since this is all he owns, and nobody can lose what is not his.

When men are inhuman, take care not to feel towards them as they do towards other humans.

Things that have a common quality ever quickly seek their kind.

How barbarous, to deny men the privilege of pursuing what they imagine to be their proper concerns and interests! Yet, in a sense, this is just what you are doing when you allow your indignation to rise at their wrongdoing; for after all, they are only following their own apparent concerns and interests. You say they are mistaken? Why then, tell them so, and explain it to them, instead of being indignant.

Aptitude found in the understanding and is often inherited. Genius coming from reason and imagination, rarely.
