ABSTRACT
This chapter could also be called "Philosophy for Physicists." Physicists are often put off by the manner in which contemporary philosophers deal with such apparently obvious notions as, for example, that of object. It seems that, when most philosophers hear the word "object," the notion of a subject for whom the object is an object immediately and spontaneously comes to their mind. In physics circles the motto "Remember that physics is an experimental science" is often heard. Prima facie, its meaning seems obvious, but it is not. The expression "intersubjective agreement" is a very general one. The agreement may be on moral values, on logical rules, on mathematical theorems, and so on. It is sufficient to observe that the objective statements of physics are not all expressed in the same way. Some of them have a form that makes it possible to interpret them as informing us directly of attributes of the things under study.
