"Now, in 1970, we are experiencing a major scientific breakthrough. The new physics, relativity, and the astrophysical theories of contemporary science had already been realized by the first part of this century. Now, in the latter part, we are arriving, with the help of the electron microscope and other new tools, at similar achievements in biology, biochemistry, and all the life sciences. Important discoveries are made yearly by small, scattered work teams all over the United States, and in other countries as well – of the magnitude of DNA in genetics, or of Urey and Miller’s work in the early fifties on the origins of life. Full mastery of the reproductive process is in sight, and there has been significant advance in understanding the basic life and death process. The nature of ageing and growth, sleep and hibernation, the chemical functioning of the brain and the development of consciousness and memory are all beginning to be understood in their entirety. This acceleration promises to continue for another century, or however long it takes to achieve the goal of Empiricism: total understanding of the laws of nature."
