Whether any event whatsoever, and Volition in particular, can come to pass without a Cause of its existence.
Before I enter on any argument on this subject, I would explain how I would be understood, when I use the word Cause in this discourse; since, for want of a better word, I shall have occasion to use it in a sense which is more extensive than that in which it is sometimes used. The word is often used in so restrained a sense as to signify only that which has a positive efficiency or influence to produce a thing, or bring it to pass. But there are many things which have no such positive productive influence; which yet are Causes in this respect, that they have truly the nature of a reason why some things are, rather than others; or why they are thus, rather than otherwise. Thus the absence of the sun in the night, is not the Cause of the fall of dew at that time, in the same manner as its beams are the cause of the ascent of vapors in the day-time; and its withdrawment in the winter, is not in the same manner the Cause of the freezing of the waters, as its approach in the spring is the cause of their thawing. But yet the withdrawment or absence of the sun is an antecedent, with which these effects in the night and winter are connected, and on which they depend; and is one thing that belongs to the ground and reason why they come to pass at that time, rather than at other times; though the absence of the sun is nothing positive, nor has any positive influence.
It may be further observed, that when I speak of connexion of Causes and effects, I have respect to moral Causes, as well as those that are called natural in distinction from them. Moral Causes may be Causes in as proper a sense as any Causes whatsoever; may have as real an influence, and may as truly be the ground and reason of an Event’s coming to pass.
Therefore I sometimes use the word Cause, in this inquiry, to signify any antecedent, either natural or moral, positive or negative, on which an Event, either a thing, or the manner and circumstance of a thing, so depends, that it is the ground and reason, either in whole, or in part, why it is, rather than not; or why it is as it is, rather than otherwise; or, in other words, any antecedent with which a consequent Event is so connected, that it truly belongs to the reason why the proposition which affirms that Event is true; whether it has any positive influence, or not. And agreeably to this, I sometimes use the word effect for the consequence of another thing, which is perhaps rather an occasion than a Cause, most properly speaking.
I am the more careful thus to explain my meaning, that I may cut off occasion, from any that might seek occasion to cavil and object against some things which I may say concerning the dependence of all things which come to pass, on some Cause, and their connexion with their Cause.
Having thus explained what I mean by Cause, I assert, that nothing ever comes to pass without a Cause. What is self-existent must be from eternity, and must be unchangeable: but as to all things that begin to be, they are not self-existent, and therefore must have some foundation of their existence without themselves.—That whatsoever begins to be, which before was not, must have a Cause why it then begins to exist, seems to be the first dictate of the common and natural sense which God hath implanted in the minds of all mankind, and the main foundation of all our reasonings about the existence of things, past, present, or to come.
And this dictate of common sense equally respects substances and modes, or things and the manner and circumstances of things. Thus, if we see a body which has hitherto been at rest, start out of a state of rest, and begin to move, we do as naturally and necessarily suppose there is some Cause or reason of this new mode of existence, as of the existence of a body itself which had hitherto not existed. And so if a body, which had hitherto moved in a certain direction, should suddenly change the direction of its motion; or if it should put off its old figure, and take a new one; or change its color: the beginning of these new modes is a new Event, and the human mind necessarily supposes that there is some Cause or reason of them.
If this grand principle of common sense be taken away, all arguing from effects to causes ceaseth, and so all knowledge of any existence, besides what we have by the most direct and immediate intuition, particularly all our proof of the being of God, ceases: we argue His being from our own being, and the being of other things, which we are sensible once were not, but have begun to be; and from the being of the world, with all its constituent parts, and the manner of their existence; all which we see plainly are not necessary in their own nature, and so not self-existent, and therefore must have a Cause. But if things, not in themselves necessary, may begin to be without a Cause, all this arguing is vain.
