"If motives be of very different kinds, with regard to strength and influence, which we feel to be the case; it is involved in the very idea of the strongest motive, that it must have the strongest effect in determining the mind. This can no more be doubted of, than that, in a balance, the greate...

"In other cases, where the field of choice is wider, and where opposite motives counterbalance and work against each other, the mind fluctuates for a while, and feels itself more loose: but, in the end, must as necessarily be determined to the side of the most powerful motive, as the balance, aft...

"The mind, therefore, in producing the vital and other involuntary motions, does not act as a rational, but as a sentient principle; which, without reasoning upon the matter, is as necessarily determined by an ungrateful sensation or stimulus affecting the organs, to exert its power, in bringing ...
