THE UNFATHOMED UNIVERSE 35 



so as to exclude them,-that is a question of method,-but 

 to think of leaving them out in our total interpretation of 

 our experience is to allow the light that is in us to be 

 darkened. Similarly, although there is great difference of 

 opinion in regard to the philosophy of the beautiful, there 

 s general agreement that our total outlook on Nature is 

 to be distrusted if the fact of beauty has been ignored. 

 Feeling is to be excluded from scientific investigation, but 

 must be allowed to operate in our philosophical synthesis 

 rhaps we may say that feeling supplies the mortar in 

 which are laid the stones contributed by Natural Science 



There are several hopeful indications of an advance 

 towards a philosophical order of Nature. The first is the 

 increasing correlation of the sciences, which are parts of 

 one endeavour to understand the order of Nature and Man's 

 life m its midst. The sciences work into one another's hands 

 n correlation, and this has always been fruitful, as is well 

 illustrated by the transforming and vitalising of chemistry 

 after it joined hands with physics. The scientific study 

 rf animal behaviour, still in the freshness of its youth, shows 

 us the effectiveness of a combined attack-psychological and 

 biological-on a difficult set of problems. The autonomy 

 lology is not inconsistent with its correlation-mpmW 

 n tmperio-with chemistry and physics on the one hand 

 1 psychology and sociology on the other. While the 

 sciences are separated off for the sake of clearness, because 

 :hey pursue different methods, use different tools, and sum 

 up m different kinds of formulae, they work into one another's 

 hands, and they are simply different modes of one rational 

 inquiry. Their mutual influence is increased, not decreased
