Santiago Ramón y Cajal (May 1, 1852–October 17, 1934)

 Cajal takes care to note that while hypotheses have their use “as inspiration during the planning stage of an investigation, and for stimulating new fields of investigation,” the theorist’s mistake is a blind attachment to her theories not as a means to truth but as an end of intellectual labor:

One must distinguish between working hypotheses … and scientific theories. The hypothesis is an interpretative questioning of nature. It is an integral part of the investigation because it forms the initial phase, the virtually required antecedent. But to speculate continuously — to theorize just for its own sake, without arriving at an objective analysis of phenomena — is to lose oneself in a kind of philosophical idealism without a solid foundation, to turn one’s back on reality.

Let us emphasize again this obvious conclusion: a scholar’s positive contribution is measured by the sum of the original data that he contributes. Hypotheses come and go but data remain. Theories desert us, while data defend us. They are our true resources, our real estate, and our best pedigree. In the eternal shifting of things, only they will save us from the ravages of time and from the forgetfulness or injustice of men. To risk everything on the success of one idea is to forget that every fifteen or twenty years theories are replaced or revised. So many apparently conclusive theories in physics, chemistry, geology, and biology have collapsed in the last few decades! On the other hand, the well-established facts of anatomy and physiology and of chemistry and geology, and the laws and equations of astronomy and physics remain — immutable and defying criticism
