What does “self-love” mean?
I think self-love is a pleasant word for vanity. Self-love means that one loves oneself more than anything else; and what he implies by this, you see, are exactly those reactions of a vanity which is vexed when one is not appreciated at one’s true worth, when one does not receive the praise he thinks he deserves, or the reward he believes he has earned, and when one is not complimented for everything he does. Indeed, all these movements come from dissatisfaction, because one doesn’t receive what he hoped to, what he thought he deserved to receive!
