“A remark may be made here, applicable alike to science and to practice. Originality in either takes two form--observation or experiment on the one hand, and the identifying processes of abstraction, induction, and deduction on the other. In the first, the bodily activities and the senses are requisite; the last are the purely intellectual forces. It is not by high intellectual force that a man discovers new countries, new plants, new properties of objects; it is by putting forth an unusual force of activity, adventure, inquisitorial and persevering search. All this is necessary in order to obtain the observations and facts in the first instance; when these are collected in sufficient number, a different aptitude is brought to bear. By identifying and assimilating the scattered materials, general properties and general truths are obtained, and these may be pushed deductively into new applications; in all which a powerful reach of similarity is the first requisite; and this may be owned by men totally destitute of the active qualities necessary for observation and experiment.” The Chief Impulse in Discovery. In “The Hazard of New Fortunes” Mr. W. D. Howells depicts a man of force who, without education, becomes rich. He has little patience with poor men, who, he says, “don’t get what they want because they don’t want it bad enough.” The rough old Westerner, Dryfoos, was sound in his view. Success in discovery as in money-making is as much a matter of passion as of intelligence, says Mr. O. F. Cook:-- “The first and most essential preliminary for a successful investigation is an interest in the question, and any method which tends to diminish or relax interest is false and futile. Diligence in learning the facts of a science is a distinctly unfavorable symptom in a would-be investigator when unaccompanied by a vital constructive interest. That a student hoards facts does not mean that he will build anything with them. Intellectual misers are common, and are quite as unprofitable as the monetary variety. A scientific specialist may have vast knowledge and life-long experience, and yet may never entertain an original idea or make a new rift in the wall of the unknown which baffled his predecessors. Indeed, such men commonly resent a readjustment of the bounds of knowledge as an interference with their vested capital of erudition.
