Christian may enjoy, or the oriental pantheist indulge in, their receipts for equanimity are expedients which seem almost crude in their simplicity. Please observe, however, that I am not yet pretending finally to _judge_ any of these attitudes. I am only describing their variety. The securest way to the rapturous sorts of happiness of which the twice‐ born make report has as an historic matter of fact been through a more radical pessimism than anything that we have yet considered. We have seen how the lustre and enchantment may be rubbed off from the goods of nature. But there is a pitch of unhappiness so great that the goods of nature may be entirely forgotten, and all sentiment of their existence vanish from the mental field. For this extremity of pessimism to be reached, something more is needed than observation of life and reflection upon death. The individual must in his own person become the prey of a pathological melancholy. As the healthy‐minded enthusiast succeeds in ignoring evil’s very existence, so the subject of melancholy is forced in spite of himself to ignore that of all good whatever: for him it may no longer have the least reality. Such sensitiveness and susceptibility to mental pain is a rare occurrence where the nervous constitution is entirely normal; one seldom finds it in a healthy subject even where he is the victim of the most atrocious cruelties of outward fortune. So we note here the neurotic constitution, of which I said so much in my first lecture, making its active entrance on our scene, and destined to play a part in much that follows. Since these experiences of melancholy are in the first instance absolutely private and individual, I can now help myself out with personal documents. Painful indeed they will be to listen to, and there is almost an indecency in handling them in public. Yet they lie right in the middle of our path; and if we are to touch the psychology of religion at all seriously, we must be willing to forget conventionalities, and dive below the smooth and lying official conversational surface. One can distinguish many kinds of pathological depression. Sometimes it is mere passive joylessness and dreariness, discouragement, dejection, lack of taste and zest and spring. Professor Ribot has proposed the name _anhedonia_ to designate this condition.
