γ. In the last place, opinion is nothing but the reference of that general conception, which we have within us, to an object, a perception, or to the testimony of the senses; and that is the passing of a judgment. For in a conception we have anticipated that which comes directly before our eyes; and by this standard we pronounce whether something is a man, a tree, or not. “Opinion depends on something already evident to us, to which we refer when we ask how we know that this is a man or not. This opinion is also itself termed conception, and it may be either true or false:—true, when what we see before our eyes is corroborated or not contradicted by the testimony of the conception; false in the opposite case.”[151] That is to say, in opinion we apply a conception which we already possess, or the type, to an object which is before us, and which we then examine to see if it corresponds with our mental representation of it. Opinion is true if it corresponds with the type; and it has its criterion in perceiving whether it repeats itself as it was before or not. This is the whole of the ordinary process in consciousness, when it begins to reflect. When we have the conception, it requires the testimony that we have seen or still see the object in question. From the sensuous perceptions blue, sour, sweet, and so on, the general conceptions which we possess are formed; and when an object again comes before us, we recognize that this image corresponds with this object. This is the whole criterion, and a very trivial process it is; for it goes no further than the first beginnings of the sensuous consciousness, the immediate perception of an object. The next stage is without doubt this, that the first perception forms itself into a general image, and then the object which is present is subsumed under the general image. That kind of truth which anything has of which it can only be said that the evidence of the senses does not contradict it, is possessed by the conceptions of the unseen, for instance, the apprehension of heavenly phenomena: here we cannot approach nearer, we can see something indeed, but we cannot have the sensuous perception of it in its completeness; we therefore apply to it what we already know by other perceptions, if there is but some circumstance therein which is also present in that other perception or conception (_supra_, p. 282).
