Miguel de Unamuno Quote
In books of psychology written from the spiritualist point of view, it is customary to begin the discussion of the existence of the soul as a simple substance, separable from the body, after this style: There is in me a principle which thinks, wills and feels... Now this implies a begging of the question. For it is far from being an immediate truth that there is in me such a principle; the immediate truth is that I think, will and feel. And I — the I that thinks, wills and feels — am immediately my living body with the states of consciousness which it sustains. It is my living body that thinks, wills and feels.
