In reply to your ? "when Socr. discovered that philos. is preparation for death" -- well the answer is simple: First, the Apology is not Plato's philosophy, rather actual history as remembered by Plato! Second: Plato was an enlightened individual and thus had knowledge of the spirit worlds, hence he knew of the utmost relevance of death since being enlightened, most probably by Socrates when he was initiated into the Elysian mysteries... At least this is my opinion which I'd say I share with Schleiermacher, the best translator of Plato.
