I am approached with the most opposite opinions and advice, and that by religious men, who are equally certain that they represent the Divine will. ... I hope it will not be irreverent for me to say that if it is probable that God would reveal his will to others, on a point so connected with my duty, it might be supposed he would reveal it directly to me...

[Heraclitus] did not require humans or their sort of knowledge, since everything into which one may inquire he despises [as being] in contrast [to his own] inward-turning wisdom.

The pinnacle of military deployment approaches the formless: if it is formless, then even the deepest spy cannot discern it nor the wise make plans against it.
