"The first thing that the human species has to do to prepare itself for the cosmic office to which it finds itself appointed is to explore human nature, to find out what are the possibilities open to it ... The great men of the past have given us glimpses of what is possible in the way of personality, of intellectual understanding, of spiritual achievement, of artistic creation. But these are scarcely more than Pisgah glimpses. We need to explore and map the whole realm of human possibility, as the realm of physical geography has been explored and mapped. How to create new possibilities for ordinary living? What can be done to bring out the latent capacities of the ordinary man and woman for understanding and enjoyment; to teach people the techniques of achieving spiritual experience ; to develop native talent and intelligence in the growing child, Instead of frustrating or distorting them?"

“This earth is one of the rare spots in the cosmos where mind has flowered. Man is a product of nearly three billion years of evolution, in whose person the evolutionary process has at last become conscious of itself and its possibilities. Whether he likes it or not, he is responsible for the whole further evolution of our planet.”

“The last two thousand years have seen the development of elaborate monotheistic theologies; but in the process their single God has broken into many, or at least has assumed a number of distinct and indeed sometimes actively hostile forms; and their nominal universalism has degenerated into competition for the possession of absolute truth.”

“Religion in some form is a universal function of man in society, the organ for dealing with the problems of destiny, the destiny of individual men and women, of societies and nations, and of the human species as a whole. Religions always have some intellectual or ideological framework, whether myth or theological doctrine; some morality or code of behaviour, whether barbaric or ethically rationalized; and some mode of ritualized or symbolic expression, in the form of ceremonial or celebration, collective devotion or thanksgiving, or religious art...”

“What we now need is a multitude of participants to take part in the great discussion and to join in the search for the larger truth and the more fruitful patterns of belief which we confidently believe is waiting to be elicited.”

“In the evolutionary pattern of thought, there is neither need nor room for the supernatural. The earth was not created; it evolved. So did all the animals and plants that inhabit it, including our human selves, mind and soul as well as brain and body. So did religion.”

“If I am to be remembered, I hope it will not be primarily for my specialized scientific work, but as a generalist; one to whom, enlarging Terence's words, nothing human and nothing in external nature was alien.”
