Abstract
We can assent to a proposition, build a theory around it, base our actions on it, and affirm its truth—without ever taking it to heart. This frequently happens, for example, to recipients of bad news who figure out what is entailed by the news, make appropriate plans, and pass the news on to others—all without really "taking it in." It happens to those who accept a scientific claim without abandoning their more private views of how things work, and it happens to members of a jury who confidently arrive at a verdict of "guilty" yet remain, on some deeper level, unconvinced. Conversely, people may dismiss their prejudices as mere prejudices while continuing to hold onto them, and a friend may acknowledge a remark to be innocuous yet be offended. Such phenomena are widespread, diverse, and philosophically intriguing. They are not simply cases of weak versus strong belief, or belief that something has a low probability versus a high probability ; nor are they cases of accepting on authority what we only partially understand. Rather, in each case, there is certain lack of depth to one's beliefs.
