Habit for all its power over or lives, is weightless, it has no inertia, no real power over time and hence over death. For all that we do to add something substantial to our being we add nothing at all, our operations work exclusively on our belief. However solipsistic you may be, you can't actually doanything with that philosophy, it provides no collateral for being. Death is certain but unprovable; it is the strangest of the transcendentals, the most intimate and the most unapproachable.
