The Inductive Method being thus defective as a Scientific guide, in the most important requirement of Science, it is unnecessary to enter into an exposition of minor defects, not the least of which is the _slowness_ with which conclusions must necessarily be arrived at, when they are reached only by the gradual accumulation of Facts and the derivation of a Law from these. A Method or a Process which lacks that which is the very essence of Science--the power of making _known_, of introducing _certainty_ into investigation, may be an important factor in the _true Scientific_ Method, but cannot constitute the _Method itself_, or its _leading_ feature. Let it not be understood, however, that in bringing the Inductive Method in Science to the ordeal of a critical examination, it is designed to detract from its just dues or to depreciate its true value. Science is preeminently severe in its probings; and that which, asserts its claim to the highest Scientific position, and affects to be the only guide to exact knowledge, cannot expect anything less than the most rigorous inquiry into the validity of such claim, and the most peremptory insistence upon the production of proper credentials before so lofty a seat be accorded it. If inquiry discovers deficiencies in its character, Science should rejoice that truth is vindicated, and that, by correctly understanding the nature and powers of their present guide, Scientific men may avoid being tempted to consider it as competent to conduct them into regions where the blind must inevitably be leading the blind, and both be in danger of the ditch. If the devotees of the Inductive Method have in their enthusiasm set up claims for it which cannot be substantiated, they must not blame the rigorous hand, which, in the service of Science, unmasks their idol and exhibits its defects, but rather impute to their own deviation from the severity of Scientific truth, the disappointment which they may experience. The question of Method lies at the foundation of all Science. Until it is thoroughly understood, until the exact character of all our Methods or Processes is definitely and rightly apprehended, there can be no full understanding of the true nature of Science, and, hence, no critical and exact line drawn between that which is Science and that which is not.
