I have endeavoured to prove that there is no real, physical, or essential difference between the motives by which we are naturally impelled to the pursuit of our own welfare and that of others. The truth of this paradox, great as it seems, may be brought to a very fair test: namely, the being able to demonstrate that the doctrine of self-interest, as it is commonly understood, is in the nature of things an absolute impossibility; and, the being able to account for that hypothesis,—that is, for the common feeling and motives of men from habits, and a confused association of ideas aided by the use of language. If others cannot answer my reasons, and if I can account for their prejudices, I should not be justified in hastily relinquishing my opinion, merely on account of its singularity. It may not be improper briefly to recapitulate the former argument as far as it proceeded. I am far from denying that there is a difference between real or physical impulses and ideal motives, but I contend that this distinction is quite beside the present purpose. For self-love properly relates to action, and all action relates to the future, and all future objects are ideal, and the interest we take in all such objects, and the motives to the pursuit of them are ideal too. The distinction between self-love and benevolence, therefore, as separate principles of action, cannot be founded on the difference between real and imaginary objects, between physical and rational motives, inasmuch as the motives and objects of the one and the other are equally ideal things. Whether we voluntarily pursue our own good or that of another, we must inevitably pursue that which is at a distance from us, something out of ourselves, abstracted from the being that acts and wills, and that is incompatible always with our present sensation or physical existence. Self-love, therefore, as the actuating principle of the mind, must imply the efficacy and operation of the imagination of the remote ideas of things, as connected with voluntary action, and the most refined benevolence, the greatest sacrifices of natural affection, of sincerity, of friendship, or humanity, can imply nothing more. The notion of the necessity of actual objects or impressions as the motives to action could not so easily have gained ground as an article of philosophical faith, but from a perverse distinction of the use of the idea to abstract definitions or external forms, having no reference to the feelings or passions; and again from associating the word _imagination_ with merely fictitious situations and events such as never have a real existence, and which consequently do not admit of action. If then self-love, even the most gross and palpable, can only subsist in a rational and intellectual nature, not circumscribed within the narrow limits of animal life, or of the ignorant present time, but capable of giving life and interest to the forms of its own creatures, to the unreal mockeries of future things, to
