What is the difference between these two situations?
- A subject thinks she knows somebody's name. However, when asked she cannot recall it immediately. After some efforts, the name is coming and she reports it. Normally, regardless this apparent difficulty to reproduce the word, we say about this situation "the subject knows this name".
- The subject has two numbers and is calculating their product (i.e. these are two sides of a rectangle and she is asked to find its area). In this situation, we do not say that the subject knows the product of two numbers until she has calculated it.
Why these situations differ? There is much similarity between them. First, the two numbers and the multiplication rule together are equivalent to the final product - in some sense they encapsulate it; therefore, it seems justifiable to say that the subject has it. In both situations, the process passes in the subject's head without any external help or additional information. The efforts are comparable. In both cases, there are periods when the subject is incapable to give an answer. Why 1 is "situation of knowledge" and 2 is not?
