Perry Berens

“Any philosophy, whether of a religious or political nature - and sometimes the dividing line is hard to determine - fights less for the negative destruction of the opposing ideology than for the positive promotion of its own. Hence its struggle is less defensive than offensive. It therefore has the advantage even in determining the goal, since this goal represents the victory of its own idea, while, conversely,it is hard to determine when the negative aim of the destruction of a hostile doctrine may be regarded as achieved and assured. For this reason alone, the philosophy's offensive will be more systematic and also more powerful than the defensive against a philosophy, since here, too, as always, the attack and not the defence makes the decision. The fight against a spiritual power with methods of violence remains defensive, however, until the sword becomes the support,the herald and disseminator, of a new spiritual doctrine.”
