and which, blended together in different proportions, give their form and colour to our lives. Without some other essential faculties, such as will, imagination, etc., to give effect and direction to our physical sensibility, this faculty could be of no possible use or influence; and with those other faculties joined to it, this pretended instinct of self-love will be subject to be everlastingly modified and controlled by those faculties, both in what regards our own good and that of others; that is, must itself become in a great measure dependent on the very instruments it uses. The two most predominant principles in the mind, besides sensibility and self-interest, are imagination and self-will, or (in general) the love of strong excitement, both in thought and action. To these sources may be traced the various passions, pursuits, habits, affections, follies and caprices, virtues and vices of mankind. We shall confine ourselves, in the present article, to give some account of the influence exercised by the imagination over the feelings. To an intellectual being, it cannot be altogether arbitrary what ideas it shall have, whether pleasurable or painful. Our ideas do not originate in our love of pleasure, and they cannot, therefore, depend absolutely upon it. They have another principle. If the imagination were 'the servile slave' of our self-love, if our ideas were emanations of our sensitive nature, encouraged if agreeable, and excluded the instant they became otherwise, or encroached on the former principle, then there might be a tolerable pretence for the epicurean philosophy which is here spoken of. But for any such entire and mechanical subserviency of the operations of the one principle to the dictates of the other, there is not the slightest foundation in reality. The attention which the mind gives to its ideas is not always owing to the gratification derived from them, but to the strength and truth of the impressions themselves, _i.e._ to their involuntary power over the mind. This observation will account for a very general principle in the mind, which cannot, we conceive, be satisfactorily explained in any other way, we mean _the power of fascination_. Every one has heard the story of the girl who, being left alone by her companions, in order to frighten her, in a room with a dead body, at first attempted to get out, and shrieked violently for assistance, but finding herself shut in, ran and embraced the corpse, and was found senseless in its arms.
