" To experience we refer, as the only ground of all physical 

 inquiry. But before experience itself can be used with advantage, 

 there is one preliminary step to make, which depends wholly on 

 ourselves : it is the absolute dismissal and clearing of the mind of 

 all prejudice from whatsoever source arising, and the determination 

 to stand or fall by the result of a direct appeal to facts in the first 

 instance, and of strict logical deduction from them afterwards."

" The mechanical conception of Nature very well admits of being 

 united with a teleological conception of the Universe."
