Abstract
The task of understanding Wittgenstein’s Philosophical Investigations is more like that of understanding a difficult person than of grasping difficult ideas. It makes heavy demands upon the reader. He must first of all have the patience to stare at slight variations in language-uses until they look as marked as Wittgenstein wants them to look. Then he must be prepared for what looks like impassable break-offs in line of thought. Next, if he is a philosopher, he must listen to a great many hard sayings about philosophy—some of them prepared for, others thrown in as crotchety asides. Through all this, he must also come to see that here is suggested a radically new way of looking at language. Without some grasp of this new way, he cannot hope to feel the main force of the work. Instead of trying to summarize the Investigations, therefore, I will try to draw together some of the principal ideas which seem to me to give sense and unity to its details. This will not amount to seeing the book as a whole. Also, I expect that the result will misrepresent some of those ideas, I hope not grievously.
