[MA-600]
DECEPTIVE AND YET DEFENSIBLE
Just as in order to pass by an abyss or to cross a deep stream on a plank we require a railing, not to hold fast by, for it would instantly break down with us, but to give the notion of security to the eye, so in youth we require persons who unconsciously render us the service of that railing. It is true they would not help us if we really wished to lean upon them in great danger, but they afford the tranquillising sensation of protection close to one (for instance, fathers, teachers, friends, as all three usually are).
