“By putting survival in a preeminent position, Darwin relegates high aspirations and elevated sentiments to the periphery, barely part of the landscape, while the utilitarian aspects of life are brought to the fore. This vision has had wide repercussions in an age where there is an unfortunate tendency to incline towards materialist and utilitarian philosophies. These have diffused a primordial and decisive feature in man: his spiritual evolution.” “In this work I have summarized the theories that I consider the most relevant and deserving of analysis and commentary on this subject both from the East and the West. I have no doubt that the reader’s spirit will soar following the elevated flight of these thinkers.” “In the final analysis this is the purpose of all my work: raising the spirit, lifting it out of the daily tedium and the noxious and low goals that contemporary society has to offer, presenting other realities beyond oneself that are more realistic, attractive and worthy of being lived when they are shown in the correct light. This work demonstrates other ways of seeing, nuances that open multiple windows for the human spirit into distant, bright and promising horizons.”
