PRELIMINARY DISCOURSE BEING An Investigation of the Moral Laws of Society. *
The science of morality hath for its subject, human actions, with their effects; and its end or purpose is, to regulate these actions.
To act by instinct signifies, to act by blind impulse, without having any end in view. The brute creatures act generally by instinct: the instinct of hunger prompts them to eat, and of cold to take shelter, without considering what these actions may produce. The same must be the condition of infants: for infants are not capable of any consideration: they apply to the nipple, without foreseeing that this action will relieve them from hunger; and they cry when pained, without having any view of procuring relief. But as soon as our ripened faculties unfold to us the connection between our actions and their effects, then it is that we begin to act with an intention to produce certain effects; and our actions, in that case, are means employed to bring about the effects intended.
Intention and will, though generally reckoned synonymous terms, signify different operations of the mind: will is relative to the external action; for we never act without a will to act: intention is relative to the effect; for we act in order to bring about the effect intended. It is my intention, for example, to relieve a certain person from distress by giving money: as soon as I see that person, it is my will to deliver the money: the external act of delivery follows: and the person is relieved; which is the effect intended. <2>
Some effects proceed necessarily from the action. A wound is an effect
[print edition page xxxvi]
necessarily connected with the action of stabbing a man with a sharp weapon: death is the necessary effect of throwing a person downward from the battlements of a high tower. Some effects are probable only: I labour, for example, in order to provide for my family; fight for my country, in order to repel its enemies; take physic, in order to restore my health. In such cases, the event intended does not necessarily nor always follow.
A man, when he wills to act, must at the same time intend to produce the effect that he knows to be necessarily connected with the action. But where the effect is probable only, a man may proceed to act without intending to produce the effect that follows. For example, a stone I throw at random into the market-place, may wound a man without my intending that effect.
Instinctive actions, from their very definition, exclude intention: actions that necessarily produce their effects, must imply intention: effects that are probable only, not necessary, are sometimes intended, sometimes not.
A right and a wrong, in such actions as are done intentionally to produce some effect, are universally acknowledged; and yet philosophers have been much difficulted to assign the cause of this eminent distinction. The various opinions that have been entertained about it, would be a delicate historical morsel; but come not within the compass of this short inquiry. I shall only observe, negatively, that the science of morals cannot be founded on any truths that may be discovered by reasoning: which will thus appear. As the faculty of reason is confined to the investigation of unknown truths by means of truths that are known, it is clear, that in no science can we even begin to reason, till we be provided with some data to found our reasonings upon: even in mathematics, there are certain principles or axioms perceived intuitively to be true, upon which all its demonstrations are founded. Reason is indeed of great use in morality, as well as in other sciences; but morality, like mathematics, is and must be provided with certain axioms or intuitive propositions, without which we cannot make a single step in our reasonings upon that subject; and to trace these with care and caution is the chief purpose of the present inquiry. <3>

CHAPTER I
The Moral Sense.
When we reflect upon the different branches of science, it might seem, that of all subjects human nature should be the best understood; because every man has daily opportunities to study it in his own passions, and in his own actions. But human nature, an interesting subject, is seldom left to the cool investigations of philosophy. Writers of a sweet disposition, inflamed with a warm imagination, compose man mostly or wholly of benevolent principles: others, of a cold temperament and narrow views, bring him down to be an animal entirely selfish. These systems are equally distant from truth: man is of a complex nature, endued with various principles, some selfish some social; and it is highly expedient that man should
