“You go against popular feelings; you criticise a hero, a great man who is generally believed to be above criticism. What happens? No one will answer your arguments in a rational way; rather you will be considered vainglorious. Its reason is mental insipidity. Merciless criticism and independent thinking are the two necessary traits of revolutionary thinking. … This is not constructive thinking. We do not take a leap forward; we go many steps back.
Our forefathers evolved faith in some kind of Supreme Being, therefore, one who ventures to challenge the validity of that faith or denies the existence of God, shall be called a Kafir (infidel), or a renegade. Even if his arguments are so strong that it is impossible to refute them, if his spirit is so strong that he cannot be bowed down by the threats of misfortune that may befall him through the wrath of the Almighty, he shall be decried as vainglorious.
…It is necessary for every person who stands for progress to criticise every tenet of old beliefs. Item by item he has to challenge the efficacy of old faith. He has to analyse and understand all the details. If after rigorous reasoning, one is led to believe in any theory of philosophy, his faith is appreciated. His reasoning may be mistaken and even fallacious. But there is chance that he will be corrected because Reason is the guiding principle of his life. But belief, I should say blind belief is disastrous. It deprives a man of his understanding power and makes him reactionary.
Any person who claims to be a realist has to challenge the truth of old beliefs. If faith cannot withstand the onslaught of reason, it collapses. After that his task should be to do the groundwork for new philosophy. We believe in nature and that human progress depends on the domination of man over nature. There is no conscious power behind it. This is our philosophy.”
