Love is one of the most important aspects present in our lives. We find it in our conversations, innumerable movies, songs, and in many occasions it is the person in charge of the emotions that seize us. However, the man and woman of our time conceive of love as a spontaneous feeling, falling in love or sexual desire. Inside their heads, there is not even a thought about that a "true love", in many occasions, implies sacrifice or the very negation of a particular good for the sake of the being that is loved. Hence, most people worry about the following: how can we be loved ?, and never how can we learn to love? But, why should we learn to love?

According to Aristotle, "to love is to want the good of the other as another", that is, to do everything possible to help him achieve, to be loved, his maximum perfection, the development of all his latent potentialities.

Love, when it seeks the perfection of the person it loves, all it wants is the good of it, which means "the perfect in its kind", and consequently its happiness.
That is why to "love", "seek the good of the other", "achieve perfection"; it is necessary to know the truth "conformity of thought or idea with the reality of things"; so that, with freedom, man is capable of addressing good.
Plato only says: "... Beauty, which exists eternally, is neither born nor dies, nor is it now beautiful and then not, nor beautiful here and ugly in another place, nor beautiful for these, and ugly for those. nor represent this beauty as it is represented, for example, a face or hands, or something else belonging to the body, neither as a discourse or as a science, but exists eternally by itself and with itself ... "

This is how the impossibility of the person to be able to love evil properly becomes evident. It is also true that reason can make some bad judgment; and it is for this reason that man with his freedom can decide to choose or address "that which the intellect presents him as good" even though there is another greater good.
