The Philosophy of Evolution, is a compendium of lectures presented by Rod Hemsell at the University of Human Unity in Auroville in 2008, 2009 and 2012. The main thrust of Sri Aurobindo’s yoga has always been toward an active participation in the human evolution and this is the defining concept which set Sri Aurobindo and the Mother apart from all others in the very beginning. With his extensive knowledge of philosophy and numerous philosophers and his familiarity with current science, Rod is able to guide the reader through the development of thought in these disciplines and shows us the place that Sri Aurobindo has staked out for us as the enlightened forerunner he was. These lectures are not a difficult or tedious ascent to airless heights, rather, they are instructive explorations of the broader base camps surrounding the mount; it is left to Sri Aurobindo and the Mother to guide us in our ascent. However, with this exploration of the terra firma, we become ever more confident that our guides to the snow capped peaks actually do know whereof they speak.
