The Four principles of war tactics:
Firstly, I attack only things that are triumphant - if necessary I wait until they become triumphant.
Secondly, I attack only those things against which I find no allies, against which I stand alone - against which I compromise nobody but myself.
Thirdly, I never make personal attacks - I use a personality merely as a magnifying-glass, by means of which I render a general, but elusive and scarcely noticeable evil, more apparent.
Fourthly, I attack only those things from which all personal differences are excluded, in which any such thing as a background of disagreeable experiences is lacking.
