The value of the threefold classification of mental processes into the categories of cognition, affection and conation is generally approved, and one problem concerning their relations is singled out, namely, which comes first, feeling or striving.

Psychological hedonism puts feeling first, and the hormic theory the reverse; it implies that we possess certain drives which impel us to attain certain ends, and maintains that feeling is dependent on these.

The arguments for and against the hormic theory are discussed from the intellectual, æsthetic and sensory points of view, and the conclusion is drawn that it is unlikely that the theory of psychological hedonism, which once made such vast claims and is now reduced to the doubtful tenure of one tiny fraction of its original territory, will hold out permanently even here.
