Abstract
The thesis is that a strong case may be made in favor of fundamentally different existential-humanistic psychologies. Four arguments are offered, the first two of which set aside traditional reasons for preserving a single existential-humanistic psychology. The third argument holds that there are fundamentally different existential-humanistic positions on basic questions having to do with human personality and change. The fourth argument is that significantly different programs of practical implications and applications are generated by fundamentally different existential-humanistic psychologies. As a package, these four arguments support the thesis of fundamentally different existential-humanistic psychologies.
