This philosophical enterprise has its origin in the discussions of the body-mind duality and how its comprehension, and possible overcoming, could positively influence educational thinking-doing in the 21st century. We analyze the book Experience and Nature, written by John Dewey, in its original and full version in order to look into the basis for a pragmatic Philosophy of Mind built by the author. We demonstrate how mind and body cannot be dissociated, what Dewey called body-mind and we extend this to a body-mind-environment, due to the continuity principle which postulates a physical-psychophysical-mental contínuum. The organicity of the field of mind, which demands the inextricable interaction between the organism and the environment and does not set aside feelings, emotions and habits is revealed as a rich field for the study of Education; Dewey himself did the same in the book Experience and Education, which we analyze, show how the Philosophy of Mind can benefit educational doing-thinking in the 21st century. We hope this work might help future research in the field of Education, Philosophy and Philosophy of Education as an important reference for the comprehension of the ideas exhibited in a book considered one of the best among the pragmatic tradition, but which has had its potential underappreciated hitherto in Brazil.
