_Strength of will_.--Weakness and paralysis of the will, a very dangerous disease in our times, and in most other times, consists not in the absolute loss of desire, such as takes place in the very old, but in the loss of the capacity to translate desire into deed. A diseased will is often met in violently passionate men, so that the proverb--"Say I will not, not I cannot"--does not always hold good. Man often would, but cannot. And then the force of desire instead of moving to outward creation, works inwardly. This is justly considered the most dangerous effect of the weakening of the will. For inward working is destructive working. Man does not only, to put it scientifically, fail to adapt nature to his needs, but he loses his own power of adaptability to outward circumstances. The most ordinary doctor, or even anybody, decides that he has before him a pathological case which must be treated with care. The patient is of the same opinion, whilst he still hopes. But when the treatment has had no results, the doctor draws back and speaks of the inadequacy of his science. Then what is the patient to retire upon? It is disgusting to speak of an incurable disease. So he begins to think, think, think--all the time about things of which nobody thinks. He is gradually forgotten, and gradually he forgets everything--but first of all, that widespread truth which asserts that no judgments are valid save those that are accepted and universal. Not that he disputes the truth: he _forgets it_, and there is none to remind him. To him all his judgments seem valid and important. Of course he cannot advance the principle: let all men turn from the external world into themselves. But why advance a principle at all? One can simply say: I am indifferent to the destinies of the external world. I do not want to move mountains or turn rivers aside or rearrange the map of Europe. I don't even want to go to the tobacconist to buy cigarettes. I don't want _to do_ anything. I want to think that my inaction is the most important thing on earth, that any "disease" is better than health, and so on and so on without end. To what thought's will not a man abandoned by medicine and doctors sink down! His judgments are not binding on us, that is as clear as day. But are they uninteresting? And is that paralysis, that weakness of will, a disease only?
