A moral being is one who is capable of reflecting on his past actions and their motives - of approving of some and disapproving of others.

The moral sense perhaps affords the best and highest distinction between man and the lower animals.

The moral faculties are generally esteemed, and with justice, as of higher value than the intellectual powers. But we should always bear in mind that the activity of the mind in vividly recalling past impressions is one of the fundamental though secondary bases of conscience. This fact affords the strongest argument for educating and stimulating in all possible ways the intellectual faculties of every human being.

Besides love and sympathy, animals exhibit other qualities connected with the social instincts which in us would be called moral.

Why should a Man be Moral? Because this strengthens his will.

We shall overcome because the arc of the moral universe is long, but it bends toward justice.
