Alfred Kinsey quotes

Alfred Kinsey was an American biologist and sexologist, best known for his pioneering research on human sexuality. His groundbreaking studies led to the publication of the influential Kinsey Reports, which challenged social norms of his era. He remains a central figure in the field of sexology and the ongoing conversation about sexual behavior. Here are 24 of his quotes:

Males do not represent two discrete populations, heterosexual and homosexual. The world is not to be divided into sheep and goats. Not all things are black nor all things white. It is a fundamental of taxonomy that nature rarely deals with discrete categories. Only the human mind invents categories and tries to force facts into separated pigeon-holes. The living world is a continuum in each and every one of its aspects. The sooner we learn this concerning human sexual behavior, the sooner we shall reach a sound understanding of the realities of sex.

Alfred Kinsey

The only unnatural sex act is that which you cannot perform.

Alfred Kinsey

We are the recorders and reporters of facts - not the judges of the behaviors we describe.

Alfred Kinsey

The very general occurrence of the homosexual in ancient Greece, and its wide occurrence today in some cultures in which such activity is not taboo suggests that the capacity of an individual to respond erotically to any sort of stimulus, whether it is provided by another person of the same or opposite sex, is basic in the species.

Alfred Kinsey

It cannot be too frequently emphasized that the behavior of any animal must depend upon on the nature of the stimulus which it meets, its anatomic and physiologic capacities, and its background of previous experience. Unless it has been conditioned by previous experience, an animal should respond identically to identical stimuli, whether they emanate from some part of its own body, from another individual of the same sex, or from an individual of the opposite sex.

Alfred Kinsey

With the right of the scientist to investigate most aspects of the material universe, most persons will agree; but there are some who have questioned the applicability of scientific methods to an investigation of human sexual behavior.... It is as though the dietician and biochemist were denied the right to analyze foods and the processes of nutrition, because the cooking and proper serving of food may be rated a fine art, and because the eating of certain foods has been considered a matter for religious regulation.

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).

Alfred Kinsey

Males do not represent two discrete populations, heterosexual and homosexual. The world is not to be divided into sheeps and goats. Not all things are black nor all things white.

Alfred Kinsey

It is ordinarily said that criminal law is designed to protect property and to protect persons, and if society's only interest in controlling sex behavior were to protect persons, then the criminal codes concerned with assault and battery should provide adequate protection. The fact that there is a body of sex laws which is apart from the laws protecting persons is evidence of their distinct function, namely that of protecting custom.

Alfred Kinsey

At the risk of being repetitious, I would remind the group that we have found the highest frequency of induced abortion in the group which, in general, most frequently uses contraceptives.

Alfred Kinsey

Some scientists hesitate to continue in a given field of research as soon as its application becomes apparent. This refusal to apply knowledge when it exists seems to us, however, to be as unrealistic as the attempt to apply knowledge before it exists. (page 8)

Alfred Kinsey

The impression that infra-human mammals more or less confine themselves to heterosexual activities is a distortion of the fact which appears to have originated in a man-made philosophy, rather than in specific observations of mammalian behavior. Biologists and psychologists who have accepted the doctrine that the only natural function of sex is reproduction, have simply ignored the existence of sexual activity which is not reproductive. They have assumed that heterosexual responses are a part of an animal's innate, "instinctive" equipment, and that all other types of sexual activity represent "perversions" of the "normal instincts". Such interpretations are, however, mystical. They do not originate in our knowledge of the physiology of sexual response (Chapter 15), and can be maintained only if one assumes that sexual function is in some fashion divorced from the physiologic processes which control other functions of the animal body.

Alfred Kinsey

There is a tendency to consider anything in human behavior that is unusual, not well known, or not well understood, as neurotic, psychopathic, immature, perverse, or the expression of some other sort of psychologic disturbance.

Alfred Kinsey

Cheese crumbs spread before a pair of copulating rats will distract the female but not the male.

Alfred Kinsey

Art alone develops weaklings, science alone, monsters. Somewhere, somehow, we must combine the two.

Alfred Kinsey

The heterosexuality or homosexuality of many individuals is not an all-or-none proposition.

Alfred Kinsey

If all persons with any trace of homosexual history, or those who were predominantly homosexual, were eliminated from the population today, there is no reason for believing that the incidence of the homosexual in the next generation would be materially reduced. The homosexual has been a significant part of human sexual activity since the dawn of history, primarily because it is an expression of capacities that are basic in the human animal.

Alfred Kinsey

The range of variation in the female far exceeds the range of variation in the male.

Alfred Kinsey

Few males achieve any real freedom in their sexual relations even with their wives. Few males realise how badly inhibited they are on these matters.

Alfred Kinsey

The male's difficulties in his sexual relations after marriage include a lack of facility, of ease, or of suavity in establishing rapport in a sexual situation.

Alfred Kinsey

It is amazing to observe how many psychologists and psychiatrists have accepted this sort of propaganda, and have come to believe that homosexual males and females are discretely different from persons who respond to natural stimuli. Instead of using these terms as substantives which stand for persons, or even as adjectives to describe persons, they may better be used to describe the nature of the overt sexual relations, or of the stimuli to which an individual erotically responds.
