Only one endowed with restless vitality is susceptible to pessimism. You become a pessimist --a demonic, elemental, bestial pessimist --only when life has been defeated many times in its fight against depression.
Our birth is but a sleep and a forgetting. The soul that rises with us, our life's star, hath had elsewhere its setting, and comet from afar: not in entire forgetfulness, and not in utter nakedness, but trailing clouds of glory do we come from God, who is our home.
Our children will not survive our habits of thinking, our failures of the spirit, our wreck of the universe into which we bring new life as blithely as we do. Mostly, our children will resemble our own misery and spite and anger, because we give them no choice about it. In the name of motherhood and fatherhood and education and good manners, we threaten and suffocate and bind and ensnare and bribe and trick children into wholesale emulation of our ways.
Our deeds are like children that are born to us; they live and act apart from our own will. Nay, children may be strangled, but deeds never: they have an indestructible life both in and out of our consciousness.
