The cause of justice is the cause of humanity. Its advocates should overflow with universal good will. We should love this cause, for it conduces to the general happiness of mankind.

An overflow of good converts to bad.

Mankind are always happy for having been happy; so that, if you make them happy now, you make them happy twenty years hence by the memory of it

Justice is the sum of all moral duty.

Innocence is not virtue. Virtue demands the active employment of an ardent mind in the promotion of the general good. No man can be eminently virtuous who is not accustomed to an extensive range of reflection.

Love and compassion are necessities, not luxuries. Without them, humanity cannot survive.
