not that the operation of the whole series is in itself null and void but as the efficacy of the first sensible cause is transmitted downwards by association through the whole chain. Association has been assumed as the leading principle in the operations of the human mind, indeed, the only one; forgetting first, the assertion of this theory, that nature must be the foundation of every artificial principle, and secondly that with respect to the result, even where association has had the greatest influence, habit is at best but a half-worker with nature, for in proportion as the habit becomes inveterate, we must suppose a greater number of actual impressions to have concurred in producing it[1].
Association may relate only to feelings; habit implies action, a disposition to do something. Let us suppose then that it were possible to account in this way for all those affections which relate to old objects and ideas, which depend on recalling past feelings by looking back into our memories. But the moment you introduce action (if it is any thing more than an involuntary repetition of certain motions without either end or object, a mere trick, and absence of mind) this principle can be of no use without the aid of some other faculty to enable us to apply old associated feelings to new circumstances, and to give the will a new direction.
Sir J. Mackintosh in his public lectures used to deny the existence of such a feeling as general benevolence or humanity, on the ground that all our affections necessarily owe their rise to particular previous associations, and that they cannot exist at all unless they have been excited before in the same manner by the same objects. If I were diposed to enter particularly into this question, I might say in the first place that such a feeling as general benevolence or
