INTRODUCTION. 5 



their mental microscope. As a natural result of their 

 revolt against the first vague and unscientific uses of 

 Analogy, they have gone to the opposite extreme, 

 and have become the Gradgrinds of Science, abound- 

 ing in facts, but alike destitute of any artistic or 

 constructive idea in arranging or disposing of their 

 facts, and oblivious of any underlying and deeper 

 Law which has originated the facts and guided in 

 their distribution. The Stage of Scientific Develop- 

 ment here described is the Inductive Stage. With no 

 knowledge of Universal a priori Laws, but close, pa- 

 tient and exact in isolated spheres of inquiry, and with 

 an immense array of scientific successes at its back, 

 the glory and glare of its triumph somewhat ob- 

 scures to the devotees of this school the utter want 

 of coherence, or of any spirit of systematic Unity in 

 their fragmentary pursuits. (Technically this is the 

 Ascending Wing of the Duismal Stage of the Scien- 

 tific Mental Evolution ; allied in a variety of senses 

 with Sequence or Secondisni and the number Two.) 



11. At length, the impulse of broader and pro- 

 founder thought induces us, as seekers after Unity of 

 System in the Universe, to recur to the idea of 

 Universal Underlying Principles of Analogy, carrying 

 back to the inquiry, now, for the first time, the Spirit 

 of Inductive Precision borrowed from the Second 

 Stage, so modified as to apply to this new field of 

 investigation ; to seek by positive discovery for the 

 revelation of those Laws, and for the Serial method 

 of their development, making of them a veritable 

 fountain-head of all Special Laws, a spheral expaii-
