《我們如何思維》: So far there is the same sort of situation as when one looking at a cloud is reminded of a human figure and face.Thinking in both of these cases (the cases of belief and of fancy) involves a noted or perceived fact, followed by something else which is not observed but which is brought to mind, suggested by the thing seen.One reminds us, as we say, of the other.Side by side, however, with this factor of agreement in the two cases of suggestion is a factor of marked disagreement.We do not believe in the face suggested by the cloud; we do not consider at all the probability of its being a fact.There is no reflective thought.The danger of rain, on the contrary, presents itself to us as a genuine possibility-as a possible fact of the same nature as the observed coolness.Put differently,we do not regard the cloud as meaning or indicating a face, but merely as suggesting it, while we do consider that the coolness may mean rain.In the first case, seeing an object, we just happen, as we say, to think of something else; in the second, we consider the possrbility and nature of the connection between the objecr seen and the object suggested.The seen thing is regarded as in some way the ground or basis of belief in the suggested thing; it possesses the quality of evidence. ……
