There is a foolish story told by COMBE in his Physiology of a man who had the supernatural gift of never feeling any pain, be it from cold, hunger, heat, or accident.
The rain beat upon him in vain, the keenest north wind did not chill him--he was fearless and free.

But this immunity was coupled with an inability to feel pleasure--his wine or ale was no more to his palate than water, and he could not feel the kiss of his child; and so we are told that he was soon desirous to become a creature subject to all physical sensations as before.

But it is, as I said, a foolish tale, because it reduces all that is worth living for to being warm or enjoying taste.

His mind was not affected, but that goes for nothing in such sheer sensuality.

However, a man without losing his tastes or appetites may train his Will to so master Emotion as to enjoy delight with liberty, and also exclude what constitutes the majority of all suffering with man.
It is a truth that there is very often an extremely easy, simple and prosaic way to attain many an end, which has always been supposed to require stupendous efforts.
