"...or, what, apart from the self, seems to promise to expand and intensify life." What do you think is the very basis of Rand's moral system. Life. But not just life in general, the life of man QUA man, man qua rational being, or perhaps better, man the passionate individual. What is her moral system about? It is a promise to expand and intensify your life and happiness. Even Rand's philosophy exudes the 'sexual' instinct type, once you toss aside your misconception that it is something as crude as passing out hardons.
