has always some object that it applies to; which, when we are lazy or unconcerned, we can easily change, and at pleasure transfer our thoughts to another, and from thence to a third, which has no relation to either of the former. Hence men forwardly conclude, and frequently say, nothing is so free as thought, and it were well it were so; but the contrary will be found true in several instances; and there are many cases wherein there is nothing more restive and ungovern- able than our thoughts : they will not be directed what objects to pursue, nor to be taken ofl‘ from those they have once fixed on, but run away with a man in pur- suit of those ideas they have in view, lethim do what he can, '

I call it a clog, for it hangs upon the mind so as to hinder its vigour and activity in the pursuit of other conteurplations, and advances
