# An Antidote Against Atheism/Book I/Chapter III

Chap. III.
1. That we are first to have a settled notion What God is, before we goe about to demonstrate That he is. 2. The Definition of God. 3. That there is an Idea of a Being absolutely perfect in our Minde, whether the Atheist will allow it to be the Idea of God or not. 4. That it is no prejudice to the Naturality of this Idea, that it may be framed from some occasions from without.
1. And now having premised thus much, I shall come on nearer to my present designe. In prosecution whereof it will be requisite for me, first to define What God is, before I proceed to demonstration That he is. For it is obvious for Man's reason to finde Arguments for the impossibility, possibility, probability, or necessity of the Existence of a thing, from the explication of the Essence thereof. ​And now I am come hither, I demand of any Atheist that denies there is a God, or of any that doubts whether there be one or no, what Idea or Notion they frame of that they deny or doubt of. If they will prove nice and squeamish, and profess they can frame no Notion of any such thing, I would gladly ask them, why they will then deny or doubt of they know not what. For it is necessary that he that would rationally doubt or deny a thing, should have some settled Notion of the thing he doubts of or denies. But if they profess that this is the very ground of their denying or doubting whether there be a God, because they can frame no Notion of him; I shall forthwith take away that Allegation, by offering them such a Notion as is as proper to God, as any Notion is proper to any thing else in the world.
2. I define God therefore thus, An Essence or Being fully and absolutely Perfect. I say fully and absolutely Perfect in counterdistinction to such Perfection as is not full and absolute, but the Perfection of this or that Species or Kind of finite Beings, suppose of a Lion, Horse, or Tree. But to be fully and absolutely Perfect is to be at least as Perfect as the apprehension of a man can conceive without a contradiction: for what is inconceivable or contradictious, is nothing at all to us, who are not now to wag one Atome beyond our Faculties; but what I have propounded is so far from being beyond our Faculties, that I dare appeal to any Atheist, that hath yet any command of Sense and reason lest in him, if it be not very easy and intelligible at the first sight, and that if there be a God, he is to be deemed of us such as this Idea or Notion sets forth.
5. But if he will sullenly deny that this is the proper Notion of God, let him enjoy his own humour; this yet remains undeniable. That there is in man an Idea of a Being absolutely and fully Perfect which we frame out by attributing all conceivable Perfection to it whatsoever that implies no contradiction. And this Notion is naturall and essentiall to the Soul of man, & cannot be washt out, nor conveigh'd away by any force or trick of wit whatsoever, so long as the Mind of man is not craz'd, but hath the ordinary use of her own Faculties.
4. Nor will that prove any thing to the purpose, whenas it shall be alleg'd that this Notion is not so connatural and essential to the Soul, because she framed it from some occasions from without. For all those undeniable Conclusions in Geometry which might be help'd and occasioned from something without, are so natural notwithstanding and Essentiall to the Soul, that you may as soon unsoul the Soul as divide her from perpetual assent to those Mathematical Truths, supposing no distemper nor violence offered to her Faculties. As for example, she cannot but acknowledge in her self the several distinct ideas of the five regular Bodies, as also, that it is impossible that there should be any more then five. And this Idea of a Being absolutely Perfect is as distinct and indeleble an Idea in the Soul, as the Idea of the five Regular Bodies, or any other Idea whatsoever.
It remains therefore undeniable, that there is an inseparable Idea of a Being absolutely Perfect ever residing, though not alwayes acting, in the Soul of man.
