Letters 26.2

Nevertheless, I offer thanks to myself, with you as witness; for I feel that age has done no damage to my mind, though I feel its effects on my constitution. Only my vices, and the outward aids to these vices, have reached senility; my mind is strong and rejoices that it has but slight connexion with the body. It has laid aside the greater part of its load. It is alert; it takes issue with me on the subject of old age; it declares that old age is its time of bloom.
