Purpose:

To critically evaluate one of the ideas of Evolutionary Psychology (EP), namely, the idea that with the architecture of the mind and the methodology of this kind of psychology, a theoretical bridge can be built between the natural sciences and the social sciences.

Methodology:

Philosophy’s own method is followed.

Results:

The idea of the unity of sciences originating from EP is problematic.

Limitations:

In future studies, specific EP aspects must be evaluated to know its feasibility and it will be necessary to examine other theoretical projects that attempt the unity of science.

Main findings:

EP’s attempt to unite the natural and social sciences is questioned because: 1) its vision of evolution is debatable, and 2) the current social studies about cognition are hardly compatible with EP.
