Of what value would the objective facts alone have been, even if they were collected 

 by millions, without a colligating theory which puts sou! into the scattered facts? They 

 would be as soulless as heaps of bricks and mortar are before they are built up into 

 a Cathedral. Theory founded on facls, as it should be, is of the greatest importance in 

 forming a right conception of Nature. Theories cannot flash out in all perfection. 

 They require to be mended, and time is needed for that.
