If it is a virtue to love my neighbor as a human being, it must be a virtue and not a vice-to love myself since I am a human being too. There is no concept of man in which I myself am not included. A doctrine which proclaims such an exclusion proves itself to be intrinsically contradictory. The idea expressed in the Biblical “Love thy neighbor as thyself!” implies that respect for one’s own integrity and uniqueness, love for and understanding of one’s own self, can not be separated from respect for and love and understanding of another individual. The love for my own self is inseparably connected with the love for any other self.
The affirmation of one’s own life, happiness, growth, freedom, is rooted in one’s capacity to love, i.e., in care, respect, responsibility, and knowledge. If an individual is able to love productively, he loves himself too; if he can love only others, he can not love at all.
The selfish person.. can see nothing but himself; he judges everyone and everything from its usefulness to him; he is basically unable to love. Does not this prove that concern for others and concern for oneself are unavoidable alternatives? This would be so if selfishness and self-love were identical. But.. selfishness and self-love, far from being identical, are actually opposites.
