It is possible that mankind is on the threshold of a golden age but, if so, it will be necessary first to slay the dragon that guards the door, and this dragon is religion.

Nobody expects to trust his body overmuch after the age of fifty.

Old age realizes the dreams of youth: look at Dean Swift in his youth he built an asylum for the insane, in his old age he was himself an inmate.

In youth we learn in age we understand.

Believe me, that was a happy age, before the days of architects, before the days of builders.
