Chapter 6, Footnote #01
Exciting cause, possible confusion
The exciting cause, the pleasure or pain produced by it, and the intention produced by such pleasure or pain in the character of a motive, are objects so intimately connected, that, in what follows, I fear I have not, on every occasion, been able to keep them sufficiently distinct. I thought it necessary to give the reader this warning; after which, should there be found any such mistakes, it is to be hoped they will not be productive of much confusion.
