The publication is a reprint of statements made to the House Committee on Science and Astronautics, 28 Feb.-9 Mar. 1967, and to the Senate Committee on Aeronautical and Space Sciences, 20 Apr. 1967, in support of NASA's FY 1968 authorization requests. The material also appears in the Govt. Printing Office prints of the hearings.

5. Francis Bacon, The Advancement of Learning (1605). Karl Popper presents one modern view of the role of induction in science; see, for example, Popper, Logic of Scientific Discovery, pp. 27-30, 40-42, 315. Popper points out that induction is not an element in the logic of science. To illustrate, from Newton's law of gravitation (and the accepted theory of mechanics) one can deduce Kepler's laws of planetary motion, in particular that in closed orbits the planets must move in elliptical orbits about the sun. But, even when a planet is observed to move in an elliptical orbit, one cannot conclude that Newton's inverse square law of gravitation holds. Another possibility would be that the planet is attracted to the sun by a force varying directly as the distance. Given such a force field it can be deduced that a planet in a closed orbit would move in an elliptical path. Additional considerations must be applied to choose between the two candidates. Thus, the inductive step from the particular to the general is not unique, forced by the logic of the situation, but rather requires choice among a number of likely possibilities. Of course, to be a potential candidate a proposed theory must imply, by normal deductive reasoning, the original particular the scientist is trying to "explain." This is what is meant by the assertion that whereas deduction is an essential element in the logic of science, induction is not.
