ABSTRACT
The purpose of this chapter is to state in dogmatic form certain conclusions which follow from previous discussions, together with the fuller discussions of “An Inquiry into Meaning and Truth”. More particularly, I wish to give meanings, as definite as possible, to the four words in the title of this chapter. I do not mean to deny that the words are susceptible of other equally legitimate meanings, but only that the meanings which I shall assign to them represent important concepts, which, when understood and distinguished, are useful in many philosophical problems, but when confused are a source of inextricable tangles.
