On the Sublime and Beautiful/Part IV/Chapter 2

IT is no small bar in the way of our inquiry into the cause of our passions, that the occasions of many of them are given, and that their governing motions are communicated at a time when we have not capacity to reflect on them; at a time of which all sort of memory is worn out of our minds. For besides such things as affect us in various manners, according to their natural powers, there are associations made at that early season, which we find it very hard afterwards to distinguish from natural effects. Not to mention the unaccountable antipathies which we find in many persons, we all find it impossible to remember when a steep became more terrible than a plain; or fire or water more terrible than a clod of earth; though all these are very probably either conclusions from experience, or arising from the premonitions of others; and some of them impressed, in all likelihood, pretty late. But as it must be allowed that many things affect us after a certain manner, not by any natural powers they have for that purpose, but by association; so it would be absurd, on the other hand, to say that all things affect us by association only; since some things must have been originally and naturally agreeable or disagreeable, from which the others derive their associated powers; and it would be, I fancy, to little purpose to look for the cause of our passions in association, until we fail of it in the natural properties of things.
