“Where danger shews it self, apprehension cannot, without stupidity, be wanting; where danger is, sense of danger should be; and so much fear as should keep us awake, and excite our attention, industry, and vigour; but not to disturb the calm use of our reason, nor hinder the execution of what that dictates.”
Sec. 115

Context: It is probably dangerous to use this theory of information in fields for which it was not designed, but I think the danger will not keep people from using it. In psychology, at least in the psychology of communication, it seems to fit with a fair approximation. When it occurs that the learnability of material is roughly proportional to the information content calculated | by the theory, I think it looks interesting. There may have to be modifications, of course. For example, I think that the human receiver of information gets more out of a message that is encoded into a broad vocabulary (an extensive set of symbols) and presented at a slow pace, than from a message, equal in information content, that is encoded into a restricted set of symbols and presented at a faster pace. Nevertheless, the elementary parts of the theory appear to be very useful. I say it may be dangerous to use them, but I don’t think the danger will scare us off.
