LOVE
Love, faith, and hope can not be proved by science but can be proven by us.
The spontaneous desire to satisfy the other, apart from a social order or an involuntary reaction to virtue, is an inherent condition in which things are seen as they are not.
But in spite of selfishness, we can all desire and do good to others, a consequence of the act of will and our habit, which strengthens the will to do good, a high demonstration of love, without the emotions that are secondary causes.
