An intellectual is one who is enlightened; and being an enlightened person, he has to give light to others who are in need of it. In every society, we find intellectuals such as philosophers, scientists, scholars, writers, and critics; and they, as enlightened men, have a great responsibility towards society. In a society, all cannot be intellectuals. If a time comes when all are intellectuals it would be a blessed time indeed; but intellectuals have the great responsibility of guiding others on to the right path. If today we have our civilisation and culture, if we have orders and security in life, and if our life is better that that of our primitive ancestors, it is because the intellectuals, from time to time, have been guiding humanity on the path of felicity and amity. Therefore, the intellectual should come out of his ivory tower and try to elevate others to his level."
