“My purpose here is to denounce an idea which seems to be dangerous and false.”

Light (1919), Ch. XX The Cult
Context: The idea of motherland is not a false idea, but it is a little idea, and one which must remain little.
There is only one common good. There is only one moral duty, only one truth, and every man is the shining recipient and guardian of it. The present understanding of the idea of motherland divides all these great ideas, cuts them into pieces, specializes them within impenetrable circles. We meet as many national truths as we do nations, and as many national duties, and as many national interests and rights — and they are antagonistic to each other.

Context: I put my life in danger and came here because I feel this country is in danger. People are worried. We will bring the country out of this crisis.

Context: It is the natural tendency of the ignorant to believe what is not true. In order to overcome that tendency it is not sufficient to exhibit the true; it is also necessary to expose and denounce the false. To admit that the false has any standing in court, that it ought to be handled gently because millions of morons cherish it and thousands of quacks make their livings propagating it—to admit this, as the more fatuous of the reconcilers of science and religion inevitably do, is to abandon a just cause to its enemies, cravenly and without excuse. It is, of course, quite true that there is a region in which science and religion do not conflict. That is the region of the unknowable.

Context: Humans can be literally poisoned by false ideas and false teachings. Many people have a just horror at the thought of putting poison into tea or coffee, but seem unable to realize that, when they teach false ideas and false doctrines, they are poisoning the time-binding capacity of their fellow men and women. One has to stop and think! There is nothing mystical about the fact that ideas and words are energies which powerfully affect the physico-chemical base of our time-binding activities. Humans are thus made untrue to "human nature." … The conception of man as a mixture of animal and supernatural has for ages kept human beings under the deadly spell of the suggestion that, animal selfishness and animal greediness are their essential character, and the spell has operated to suppress their REAL HUMAN NATURE and to prevent it from expressing itself naturally and freely.

Context: The idea that feminism is the first group that has ever denounced rape is a gross libel to men. Throughout history, rape has been condemned by honorable men. Honorable men do not murder; honorable men do not steal; honorable men do not rape. It goes all the way back through history. Tarquin’s rape of Lucretia caused the fall of the tyrants and the beginning of the Roman Republic. The idea that somehow suddenly feminism miraculously found out that women were being exploited and raped throughout history is ridiculous.
