I THE SEXUAL ABERRATIONS The fact of sexual need in man and animal is expressed in biology by the assumption of a "sexual impulse." This impulse is made analogous to the impulse of taking nourishment, and to hunger. The sexual expression corresponding to hunger not being found colloquilly, science uses the expression "libido."

CHAPTER IINTRODUCTION Science. Before attempting to define psychology, it will be helpful to make some inquiry into the nature of science in general. Science is knowledge; it is what we know. But mere knowledge is not science. For a bit of knowledge to become a part of science, its relation to other bits of knowledge must be found. In botany, for example, bits of knowledge about plants do not make a science of botany. To have a science of... more...

I count it a mistake of our mistaken democracy, that every man who can read print is allowed to believe that he can read all... more...

At my own University of Harvard, not a winter passes without its harvest, large or small, of lectures from Scottish, English, French, or German representatives of the... more...

This called forth as an unavoidable consequence a more lively interest on the part of various social agencies in the personality of the criminal,... more...
