The fact is that non-violence does not work in the same way as violence. It works in the opposite way. An armed man naturally relies upon his arms. A man who is intentionally unarmed relies upon the Unseen Force called God by poets, but called the Unknown by scientists. But that which is unknown is not necessarily non-existent. God is the Force among all forces known and unknown. Non-violence without reliance upon that Force is poor stuff to be thrown in the dust.
Gandhiji, Harijan, 28-6-1942
