Russell's discussion of the problems of philosophy has focused on problems directly or indirectly concerning knowledge. But the nature of philosophy is itself one of the problems of philosophy and, as Russell's addresses it in chapters 14 and 15, he has more to say about knowledge.

• Of course think about the broad topic of chapter 14 (and especially the discussion of the relation between philosophy and science at the end, ¶¶14.11-14.14). But also think about two specific points which are part of Russell's efforts to set limits on philosophy.

• The first is his discussion of Hegelian holism and the associated conception of relations (¶¶14.2-14.5)--especially points (1) and (2) of ¶14.4.

• The second is his claim that there can be no a priori knowledge of existence (¶14.10), which he had stated in a different context earlier (in ¶7.12).

• In the case of the last chapter, it is the broad ideas that you should look to. Russell's account of the value of philosophy is not uncontroversial and is an expression of the spirit of its era. It seems to be influenced by G. E. Moore's ethical ideas and is in keeping with ideas about literary and artistic modernism beginning to appear in Russell's day (in particular those associated with what is known as the "Bloomsbury group," which was also influenced by Moore's views).
