G2 INTRODUCTION. 



6. This means that philosophy is retrospective : it sums up, 

 retrospe. . ^|^ criticises, it does not prefigure the future. The correct- 

 ness of this proposition may be doubted. We shall have 

 to deal with it in another place. At present it reminds 

 us that thought, in the sense in which we take it, cannot
