This book reformulates the concept of experience according to three philosophical orientations situated in the 20th century: phenomenology, empiricism, and pragmatism. In this sense, the thought of Eduardo Nicol, the empiricism of William James and Alfred North Whitehead, and the philosophy of John Dewey converge in this text to indicate the possible relationship between experience, truth, the body, universality, and practice. Given the demands of our current situation—in which we have striven to dispense with rigid or dogmatic notions of truth, knowledge, justice, or beauty due to the potential dangers they might entail; yet, at the same time, we find ourselves in constant need of truth, knowledge, and beauty to justify and give meaning to our actions and projects—we can no longer simply construct ourselves based on traditional concepts, but neither can we leave the future to chance. It is essential that we construct ourselves and our environment from a different perspective. And we have found, precisely in experience, a starting point that can open up new possibilities for understanding ourselves and confronting the problems of truth, knowledge, and justice.
