Approbation of what? Naturally he took it to be of the system which he had worked out concerning the interrelationship of soul and body. And so he stressed more and more the mastership of the soul, the way in which vessels and organs ministered to its purposes, although those could be foiled and spoiled by selfish instincts in the mind and the animus.

Most important of all for him, he was convinced he had found the right religious philosophy. He was satisfied with the way he had fitted together the pieces of physical and spiritual information he had labored to acquire. In fact he had the comprehensive hypothesis every scientist craves, and it seemed to him to provide all the answers, bar slight details.

He was not mildly dejected now and then as every thinking human being must be at the gap between knowing and doing; it was more than that. Swedenborg was suffering. He suffered in proportion to the joy he had experienced when he perceived "the light"—an experience which, all mystics testify, makes a hypersensitive scru-
