  This is a lecture on the ethics and role of science in promoting rational and
objective thinking in society. It was delivered by Prof. Shyamal Sengupta of
Kolkata, India. Prof. Sengupta, who passed away recently, has inspired
generations of Indian physicists by his rational viewpoints on science and by
teaching his students the importance of a scientific outlook. We, some of his
former students dedicate this small corner of the archive to his fond memory.
