Abstract

Philosophy resists the extensión to man of modes of explanation that function well in the investigation of nature, without taking into account that we too are part of it. When we take that into account, however, we make possible the revitalizing of philosophy and perhaps even the solution of its most significant problems. Neuroscience in an evolutionary context, for example, transforms the problems of realism and scientific rationality. Upon considering that our brain structures – and consequently our modes of thought – are the result of a long series of adaptations to a large succession of environments, we see that natural selection could have brought about different modes of thought no less valid than ours. The result of such considerations is what I have called “evolutionary relativism”. This type of relativism is not susceptible to the traditional objections; and it provides us, in addition, the basis of a theory of relative truth.
