"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...
