The significance of this book for YA lies in the sympathetic treatment given several currently unfashionable and discredited theories: Velikovsky's theory of colliding worlds; Leary's research with the drug LSD; transmission of inherited characteristics in flatworms; extrasensory perception; the effect of prayer on plant life; and others. The author surrounds these with several chapters in which he puts forth the thesis that science has moved out from under the aegis of the Church to that of Government, with its own censorship and harassment of research. It's provocative reading for young people who've studied about Galileo and Darwin.
