I. The last General Cause of our Errors.
II. That the Idea's of things are not always present to the Mind, as soon as 'tis desir'd.
III. That all Finite Minds are liable to Error, and why.
IV. We ought not to judge that there are only Bodies or Spirits, nor that God is a Spirit, as we conceive Spirits.
WE have hitherto spoken of Errors, * 1.1 for which we can assign some occasional Cause in the Nature of the Pure Understanding, or of the Mind consider'd, as acting of it self, and in the Nature of Idea's, that is, in the manner how the Mind perceives External Objects. There now remains only to explain a Cause, which may be call'd a Universal and General Cause of all our Errors; because we conceive no Error, but what depends in some measure on it. That Cause is, That Nothing having no Idea to represent it, the Mind is induc'd to believe, that things it has no Idea of, do not Exist.
It is certain, that the general Source of our Errors, as we have already often declar'd, is, because our Judgments have more Extension than our Perceptions. For when we consider some Object, we commonly behold it only on one side, and we are not contented with judging of so much as we have consider'd, but we also judge of the whole Object. Therefore it often happens that we are deceiv'd, because, though the thing be true on that part we have examin'd it, it commonly proves false on the other, and that which we believe to be true only proves likely. Moreover it is evident, that we should not judge absolutely of things as we do, if we did not think we had consi∣der'd them on all sides, or if we did not suppose them answerable to those we have examin'd. Therefore the
