of association, or at least not immediately connected with it, intermixed themselves. I have here put together all my separate papers on these subjects, digesting them in such order as they seemed naturally to suggest; and adding such things as were necessary to make the whole appear more complete and systematical.
I think, however, that I cannot be called a system-maker, since I did not first form a system, and then suit the facts to it, but was carried on by a train of thoughts from one thing to another, frequently without any express design, or even any previous suspicion of the consequences that might arise. And this was most remarkably the case, in respect of the doctrine of necessity; for I was not at all aware, that it followed from that of association, for several years after I had begun my inquiries; nor did I admit it at last, without the greatest reluctance.
There are two things in these papers, which require a particular apology. First, The imperfect state in which they are presented to the reader. Secondly, The great freedom which I have used in respect to all orders of men in the conclusion of the Second Part.
