To prevent mistakes, it must be observed, that desire here is taken in its proper sense, namely, that internal act, which, by influencing the will, makes us proceed to action. Desire in a lax sense respects also actions and events that depend not on us, as when I desire that my friend may have a son to represent him, or that my country may flourish in<43> arts and sciences: but such internal act is more properly termed a wish than a desire.
Having distinguished passion from emotion, we proceed to consider passion more at large, with respect especially to its power of producing action.
We have daily and constant experience for our authority, that no man ever proceeds to action but by means of an antecedent desire or impulse. So well established is this observation, and so deeply rooted in the mind, that we can scarce imagine a different system of action: even a child will say familiarly, What should make me do this or that, when I have no desire to do it? Taking it then for granted, that the existence of action depends on antecedent desire; it follows, that where there is no desire there can be no action. This opens another shining distinction between emotions and passions. The former, being without desire, are in their nature quiescent: the desire included in the latter prompts one to act in order to fulfil that desire, or, in other words, to gratify the passion.
The cause of a passion is sufficiently explained above: it is that being or thing, which, by raising desire, converts an emotion into a passion. When we consider a passion with respect to its power of prompting action, that same being or thing is termed its object: a fine woman, for example, raises the passion of love, which is directed to her as its object: a man, by injuring me, raises my resentment, and becomes thereby the<44> object of my resentment. Thus the cause of a passion, and its object, are the same in different respects. An emotion, on the other hand, being in its nature quiescent, and merely a passive feeling, must have a cause; but cannot be said, properly speaking, to have an object.1
The objects of our passions may be distinguished into two kinds, general and particular. A man, a house, a garden, is a particular object: fame, esteem, opulence, honour, are general objects, because each of them comprehends many particulars. The passions directed to general objects are commonly termed appetites, in contradistinction to passions directed to particular objects, which retain their proper name: thus we say an appetite for fame, for glory, for conquest, for riches; but we say the passion of friendship, of love, of gratitude, of envy, of resentment. And there is a material difference between appetites and passions, which makes it proper to distinguish them by different names: the latter have no existence till a proper object be presented; whereas the former exist first, and then are directed to an object: a passion comes after its object; an appetite goes before it, which is obvious in the appetites of hunger, thirst, and animal love, and is the same, in the other appetites above mentioned.
By an object so powerful as to make a deep impression, the mind is inflamed, and hurried to action with a strong impulse. Where the object is less powerful, so as not to inflame the mind, no-<45>thing is felt but desire without any sensible perturbation. The principle of duty affords one instance: the desire generated by an object of duty, being commonly moderate, moves us to act calmly, without any violent impulse; but if the mind happen to be inflamed with the importance of the object, in that case desire of doing our duty becomes a warm passion.
The actions of brute creatures are generally directed by instinct, meaning blind impulse or desire, without any view to consequences. Man is framed to be governed by reason: he commonly acts with deliberation, in order to bring about some desireable end; and in that case his actions are means employed to bring about the end desired: thus I give charity in order to relieve a person from want: I perform a grateful action as a duty incumbent on me: and I fight for my country in order to repel its enemies. At the same time, there are human actions that are not governed by reason, nor are done with any view to consequences. Infants, like brutes, are mostly governed by instinct, without the least view to any end, good or ill. And even adult persons act sometimes instinctively: thus one in extreme hunger snatches at food, without the slightest consideration whether it be salutary: avarice prompts to accumulate wealth, without the least view of use; and thereby absurdly converts means into an end: and animal love often hurries to fruition, without a thought even of gratification.<46>
A passion when it flames so high as to impel us to act blindly without any view to consequences, good or ill, may in that state be termed instinctive; and when it is so moderate as to admit reason, and to prompt actions with a view to an end, it may in that state be termed deliberative.
With respect to actions exerted as means to an end, desire to bring about the end is what determines one to exert the action; and desire considered in that view is termed a motive: thus the same mental act that is termed desire with respect to an end in view, is termed a motive with respect to its power of determining one to act. Instinctive actions have a cause, namely, the impulse of the passion; but they cannot be said to have a motive, because they are not done with any view to consequences.
We learn from experience, that the gratification of desire is pleasant; and the foresight of that pleasure becomes often an additional motive for acting. Thus a child eats by the mere impulse of hunger: a young man thinks of the pleasure of gratification, which being a motive for him to eat, fortifies the original impulse: and a man farther advanced in life, hath the additional motive, that it will contribute to his health.*<47>
From these premisses, it is easy to determine with accuracy, what passions and actions are selfish, what social. It is the end in view that ascertains the class to which they belong: where the end in view is my own good, they are selfish; where the end in view is the good of another, they are social. Hence it follows, that instinctive actions, where we act blindly and merely by impulse, cannot be reckoned either social or selfish: thus eating, when prompted by an impulse merely of nature, is neither social nor selfish; but add a motive, That it will contribute to my pleasure or my health, and it becomes in a measure selfish. On the other hand, when affection moves me to exert an action to the end solely of advancing my friend’s
