Investigation of the phenomena of extrasensory perception using blind subjects

Hundreds of years of probing into the secrets of the universe have given science much knowledge concerning the universe and the laws which govern it. And foremost in this probing have been the control and manipulation of the various phenomena which seem to be a product of the operation of these laws. Science has also pentrated the depths of the human body and has revealed the secrets of its internal anatomic structure and the intricate functions of the various parts. Along with searching into the physiological side of man, there has been a good deal of searching into his psychological side-what makes man the superior member of the animal kingdom? What motivates him? What is his "mind," and what are its capabilities and its limitations? In attempting to answer these and countless other similar questions, science, having the results of much research to support it, has assumed that the mind is geared to the sense organs and is ultimately dependent upon a complex chain of principles understandable in terms of lawful and quantitative relationships. It has shied away from anything which would seem to suggest that the human mind can perceive what is going on in its environment through means other than the recognized channels of sight, sound, taste, smell, and the other receptors of the body.
