We live through myriads of seconds, yet it is always one, just one, that casts our entire inner world into turmoil, the second when (as Stendhal has described it) the internal inflorescence, already steeped in every kind of fluid, condenses and crystallizes—a magical second, like the moment of generation, and like that moment concealed in the warm interior of the individual life, invisible, untouchable, beyond the reach of feeling, a secret experienced alone. No algebra of the mind can calculate it, no alchemy of premonition divine it, and it can seldom perceive itself.
