§. 2

David Hume's theory—Sole Causes of belief and disbelief, vividness and faintness of ideas.

In the character of materials constituting the foundation of persuasion affirmative and disaffirmative—in other words in the character of causes of belief and disbelief—belief and disbelief in general and therefore in particular as applied to testimony, other principles, differing from this and from one another have been presented by other hands. Of each of them, for the purpose of illustration, viz for the purpose to plan the above account in the clearer point of view, some account of each of them may have its use: some account and in each instance in very brief one, it is supposed may suffice.

    § .2. Hume's vividness

    According to David Hume alone of any supposed matter of fact the idea which his plan in a mans mind is to a certain degree vivid, the supposed matter of fact is by that same man believed: if the vividness has not risen to that necessary degree, the matter of fact is not believed, belief in regard to it has no place.

    On this occasion the state of the mind called disbelief seems scarcely to have presented itself to his notice: by the affirmative phases of persuasion viz the opposite case belief his attention seems to have been engrossed. Had the two equally existing modes of persuasion obtained each of them that equal/share of attention which was its due, the need of looking out for some common term, equally applicable to both, such as the word persuasion would naturally have presented itself to so acute a mind.

    In respect of conception or memory or both degree of vividness the sole difference between belief and disbelief or rather between belief and un-belief. Such was Humes theory. How stands the matter of fact, as testified by memorial[?] experience? an experience to which hurried away by the warmth of the philosophical pursuit his attention could never find the opportunity for applying itself.

    §.3

    Since the publication of that work of David Hume another set of philosophers have appeared according to whose belief affirmative persuasion is not an act of the judgement, nor yet the result of a certaindegree of vividness in the idea or image of the supposed matter of fact in question but the result of the operation of a particular sort of sense a sense as much as any of the five senses a sense made for the purpose, and though not one of the five, as true as sense as any of them.

    So inadequate will the cause thus assigned be found to be to the effect produced, that unless a slight intimation were given of the necessity by which the demand for this hypothesis was produced, it may be a matter of difficulty to achieve wonder and admiration how it should ever have come into existence.

    A certain class of cases had been noted in which the authority of the judgment was found to sit uneasy. A warrant was wanted for bestowing belief upon a class of supposed facts which by the judgment it was apprehended might be were impossible.

    The idea or image—lodged by a matter of fact in the mind may to any degree be faint, and at the same time the belief of its existence of its first existence at the time and place in question be of the firmest texture. When for this or any other purpose the memory is employed to bring back into the mind such of the incidents of his life for which this sort of occasional [...?] has been provided, the degrees of vividness in which they present themselves vary upon a long scale of gradation terminating in 0 yet all of them equally accompanied with the persuasion of their existence: or if in this or that instance a doubt of the accuracy of the memory in this respect happen[s] to present itself it is not by the comparative vividness of the impression but by something very different that the doubt is suggested. Of the same matter of fact any given recollection will sometimes present itself as correct at other times as incorrect, i.e. as conformable to the original conception which formed the pattern to it, but when it presents itself as correct the impression in the mind will not be more vivid that in the opposite case.
