| But if reason has no original influence, it is impossible it can withstand any principle, which has such an efficacy, or ever keep the mind in suspence a moment. |
| Thus it appears, that the principle, which opposes our passion, cannot be the same with reason, and is only called so in an improper sense. |
| We speak not strictly and philosophically when we talk of the combat of passion and of reason. |
| Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them. |
| As this opinion may appear somewhat extraordinary, it may not be improper to confirm it by some other considerations. |
| A passion is an original existence, or, if you will, modification of existence, and contains not any representative quality, which renders it a copy of any other existence or modification. |
| When I am angry, I am actually possest with the passion, and in that emotion have no more a reference to any other object, than when I am thirsty, or sick, or more than five foot high. |
| It is impossible, therefore, that this passion can be opposed by, or be contradictory to truth and reason; since this contradiction consists in the disagreement of ideas, considered as copies, with those objects, which they represent |
| What may at first occur on this head, is, that as nothing can be contrary to truth or reason, except what has a reference to it, and as the judgments of our understanding only have this reference, it must follow, that passions can be contrary to reason only so far as they are accompanyed with some judgment or opinion. |
| According to this principle, which is so obvious and natural, it is only in two senses, that any affection can be called unreasonable. |
| First, When a passion, such as hope or fear, grief or joy, despair or security, is founded on the supposition or the existence of objects, which really do not exist. |
| Secondly, When in exerting any passion in action, we chuse means insufficient for the designed end, and deceive ourselves in our judgment of causes and effects. |
| Where a passion is neither founded on false suppositions, nor chuses means insufficient for the end, the understanding can neither justify nor condemn it. |
| It is not contrary to reason to prefer the destruction of the whole world to the scratching of my finger. |
| It is not contrary to reason for me to chuse my total ruin, to prevent the least uneasiness of an Indian or person wholly unknown to me. |
| It is as little contrary to reason to prefer even my own acknowledgeed lesser good to my greater, and have a more ardent affection for the former than the latter. |
| A trivial good may, from certain circumstances, produce a desire superior to what arises from the greatest and most valuable enjoyment; nor is there any thing more extraordinary in this, than in mechanics to see one pound weight raise up a hundred by the advantage of its situation. |
| In short, a passion must be accompanyed with some false judgment. |
| in order to its being unreasonable; and even then it is not the passion, properly speaking, which is unreasonable, but the judgment. |
| The consequences are evident. |
| Since a passion can never, in any sense, be called unreasonable, but when founded on a false supposition. |
