Rama dies, Syama dies, father dies, mother dies, he dies, she dies, etc. all these experiences may help us in the conclusion that after all man dies and therefore the conclusion man is mortal made. But the defect of this process of knowledge is that it may be that we have not seen a person who is still living even after some thousands of years. As soon as we get this information the whole conclusion that a man is mortal - is at once changed and we have to say that some men are mortal. In this way the research work of scientific thought are constantly changing because the very research work is done by person who is himself a condition by the four principles of mistake, illusion, cheating and imperfection. Therefore, the Deductive Process is more effective. Man is mortal we have heard it from very authoritative sources like the Vedas and we have accepted it.
