This open access book discusses a variety of important but unprecedented
ways in which psychology can be useful to philosophy. The early chapters
illustrate this theme via comparisons between Chinese and Western
philosophy. It is argued that the Chinese notion of a heart-mind is
superior to the Western concept of mind, but then, more even-handedly,
the relative strengths and weaknesses of Chinese and Western thought
overall are critically examined. In later chapters, the philosophical
uses of psychology are treated more specifically in relation to major
issues in Western philosophy. Michael Slote shows that empathy and
emotion play a role in speech acts (like assertion and thanking) that
speech act theory has totally ignored. Similarly, he treats the age-old
question of whether justice pays using psychological material that has
not previously been recognized. Finally, the implications of
psychological egoism are discussed in terms of some new psychological
and, indeed, human distinctions. Human life is pervaded by instincts and
aspirations that are neither egoistic nor altruistic, and recognizing
that fact can help put egoism in its place. It is less of a challenge to
morality than we have realized.
