Man has evolved in the last stages of his evolution taking advantage of the cyclical and repetitive causality, the rhythm, the pattern, the spatio temporal sequence present in nature. This had given him a large brain, conceptual thought and took making, language, social living in large groups, cumulation of his culture and experiences, mythologies, religion, behaviour codes, ethics, morals, art, dance, drama and music and other higher arts. It had also given him some noble passions like love, charity, equity, justice etc., as well as some base passions like greed, envy, vengeance, cruelty etc. By the end of 20th century man has mastered thermonuclear weapons and their delivery systems by rockets and satellites. He has also acquired mastery over the evolution of himself as well as the other species of living organisms. Whether he will use these powers for the benefit of mankind as well as the flora and fauna of this world or for its destruction depends largely on the cultivation of his noble passions and controlling his base passions. For that a proper social environment where equity and justice, love and charity should be developed. This responsibility falls on the generation who are now in their 20s and 30s.
The author studied physical sciences in Andhra University, Visakhapatnam, latter went to New York University, Bronx, N.Y. in 1961 and spent two seamsters there. Then he went to University of Missouri, Columbia, Mo. and spent two seamsters there studying engineering sciences. After his return to India in 1962 he engaged himself in some business activities for some years. For the last 15 years he was involved in the education of school children. He observed that they are not getting an integrated education. Instead, what they are getting is piece- meal and pedantic and uninteresting. They are losing the beauty of the woods for the details of the trees. Hence this book is written primarily for the school leaving and college going students as well as lay men who have an interest in understanding the world around them in a rationalistic fashion. No more scientific knowledge is assumed in readers than what is found in school level text books.
