Arthur Schopenhauer,
On the Fourfold Root of the Principle of Sufficient Reason…
“ Now, with reference to the function which effects this, it is quite immaterial whether the intellect turns gravitation ingeniously to account, and makes it serve its purpose by stepping in just at the right time, or whether it brings the collective or the individual propensities of men into play for its own ends. In its practical application we call the Understanding shrewdness or, when used to outwit others, cunning; when its aims are very insignificant, it is called slyness and, if combined with injury to others, craftiness. ”
