Science is an immensely prosperous and successful enterprise – as religion is not, nor economics, nor philosophy itself – because it is the outcome of applying a certain sure and powerful method of discovery and proof to the investigation of natural phenomena: The Scientific Method. The scientific method is not deductive in character: it is a well-known fallacy to regard it as such: but it is rigorous nevertheless, and logically conclusive. Scientific laws are mductive in origin. An episode of scientific discovery begins with the plain and unembroidered evidence of the senses – with innocent, unprejudiced observation, the exercise of which is one of the scientist’s most precious and distinctive faculties – and slowly builds upon it a great mansion of natural law. The word experiment has also changed its meaning. The concept of induction was entrenched into scientific methodology through the formidable advocacy of John Stuart Mill.
