Studies in the Evolutionary Psychology of Feeling

Of all the sciences psychology is, perhaps, the most imperfect. If a science is a body of knowledge obtained by special research and accepted by the general consensus of specialists, then psychology is so defective as to scarcely merit the name of science. This want of consensus is everywhere apparent, and must especially impress any one who compares the lack of harmony in manuals of psychology with the practical unanimity in manuals of botany, geology, physics, and other sciences. Even in the most fundamental points there is no agreement, as will be evident in a most summary statement.
