Some scientists hesitate to continue in a given field of research as soon as its application becomes apparent. This refusal to apply knowledge when i… - Alfred Kinsey

There is an honesty in science which demands that the best means be used for the determination of truth. Certainly there are many sorts of truth in the universe, and many aspects of truth must be taken into account if man is to live most effectively in the social organization to which he belongs. But in regard to matter---the stuff of which both non-living materials and living organisms are made---scientists believe that there is no better way of obtaining information than that provided by human sense organs. No theory, no philosophy, no body of theology, no political expediency, no wishful thinking, can provide a satisfactory substitute for the observation of material objects and of the way in which they behave. (page 9).

There is an honesty in science which leads to a certain acceptance of reality. There are some who, finding the ocean an impediment to the pursuit of their designs, try to ignore its existence. If they are unable to ignore it because of its size, they try to legislate it out of existence, or try to dry it up with a sponge. They insist that the latter operation would be possible if enough sponges were available, and if enough persons would wield them. There is no ocean of greater magnitude than the sexual function, and there are those who believe that we would do better if we ignored its existence, that we should not try to understand its material origins, and that if we sufficiently ignore it and mop at the flood of sexual activity with new laws, heavier penalties, more pronouncements, and greater intolerances, we may ultimately eliminate the reality. (page 10).

The inherent physiologic capacity of an animal to respond to any sufficient stimulus seems, then, the basic explanation of the fact that some individuals respond to stimuli originating in other individuals of their own sex-and it appears to indicate that every individual could so respond if the opportunity offered and one were not conditioned against making such responses. There is no need of hypothesizing peculiar hormonal factors that make certain individuals especially liable to engage in homosexual activity, and we know of no data which prove the existence of hormonal factors (p. 758). There are no sufficient data to show that specific hereditary factors are involved. Theories of childhood attachments to one or the other parent, theories of fixation at some infantile level of sexual development, interpretations of homosexuality as neurotic or psychopathic behavior or moral degeneracy, and other philosophic interpretations are not supported by scientific research, and are contrary to the specific data on our series of female and male histories.
