§116

Wittgenstein lists some of the concepts that philosophers have concerned themselves with - thinking that they are grasping the essence of the thing in question. Concepts like 'knowledge', 'being', 'object', 'I', 'proposition', and 'name' are ones that philosophers have concerned themselves with. Philosophers have tried to pinpoint the essential features of knowledge, being etc. But an examination of the ways in which these words are actually used would reveal that they have a variety of uses.

Wittgenstein's new method (or methods) is to focus on the everyday use of words and so to remove the illusion that there is some essential feature of each of the items on the list.
