Sexual Quotes (27 quotes)

… however useful the words may have been in the past, they have now become handicaps to the further development of knowledge. Words like botany and zoology imply that plants and animals are quite different things. … But the differences rapidly become blurred when we start looking at the world through a microscope. … The similarities between plants and animals became more important than their differences with the discoveries that both were built up of cells, had sexual reproduction,… nutrition and respiration … and with the development of evolutionary theory.
In The Forest and the Sea (1960), 7.

“Auto erotism,” … spontaneous solitary sexual phenomena of which genital excitement during sleep may be said to be the type.
Psychology of Sex (1933), 91.

[I doubt that in today's world, I and Francis Crick would ever have had our Eureka moment.] I recently went to my staircase at Clare College, Cambridge and there were women there! he said, with an enormous measure of retrospective sexual frustration. There have been a lot of convincing studies recently about the loss of productivity in the Western male. It may be that entertainment culture now is so engaging that it keeps people satisfied. We didn't have that. Science was much more fun than listening to the radio. When you are 16 or 17 and in that inherently semi-lonely period when you are deciding whether to be an intellectual, many now don't bother.
(Response when asked how he thought the climate of scientific research had changed since he made his discovery of the structure of life in 1953.)

Among all types of sexual activity, masturbation is ... the one in which the female most frequently reaches orgasm.
Sexual Behavior in the Human Female (1953), 132.
Science quotes on:  |  Activity (218)  |  Female (50)  |  Masturbation (3)  |  Most (1728)  |  Orgasm (2)  |  Sex (68)  |  Type (171)

Animals generally seem naturally disposed to … intercourse at about the same period of the year, and that is when winter is changing into summer…. In the human species, the male experiences more under sexual excitement in winter, and the female in summer.
Aristotle
In The Works of Aristotle: Historia Animalium (350 BC), (The History of Animals), Book V, Part 8, 542a20 translated in William David Ross and John Alexander Smith (eds.), D’Arcy Wentworth Thompson (trans.), (1910), Vol. 4, 27-28

Courtship, properly understood, is the process whereby both the male and the female are brought into that state of sexual tumescence which is a more or less necessary condition for sexual intercourse. The play of courtship cannot, therefore, be considered to be definitely brought to an end by the ceremony of marriage; it may more properly be regarded as the natural preliminary to every act of coitus.
Studies in the Psychology of Sex (1921), Vol. 3, 239.
Science quotes on:  |  Act (278)  |  Both (496)  |  Condition (362)  |  Consider (428)  |  End (603)  |  Female (50)  |  Marriage (39)  |  More (2558)  |  More Or Less (71)  |  Natural (810)  |  Necessary (370)  |  Process (439)  |  Regard (312)  |  Sex (68)  |  State (505)  |  Understood (155)

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.
Sexual Behavior in the Human Male (1948), 545.
Science quotes on:  |  Badly (32)  |  Freedom (145)  |  Inhibition (13)  |  Male (26)  |  Matter (821)  |  Sex (68)  |  Wife (41)

From the sexual, or amatorial, generation of plants new varieties, or improvements, are frequently obtained; as many of the young plants from seeds are dissimilar to the parent, and some of them superior to the parent in the qualities we wish to possess... Sexual reproduction is the chef d'oeuvre, the master-piece of nature.
Phytologia. (1800), 115, 103.

I can still recall vividly how Freud said to me, “My dear Jung, promise me never to abandon the sexual theory. That is the most essential thing of all. You see, we must make a dogma of it, an unshakable bulwark” … In some astonishment I asked him, “A bulwark-against what?” To which he replied, “Against the black tide of mud”—and here he hesitated for a moment, then added—“of occultism.”
Carl Jung
Memories, Dreams, Reflections (1963), 147-8.

Imagine Aristotle revivified and visiting Manhattan. Nothing in our social, political, economic, artistic, sexual or religious life would mystify him, but he would be staggered by our technology. Its products—skyscrapers, cars, airplanes, television, pocket calculators—would have been impossible without calculus.
In book review, 'Adventures Of a Mathematician: The Man Who Invented the H-Bomb', New York Times (9 May 1976), 201.

It may very properly be asked whether the attempt to define distinct species, of a more or less permanent nature, such as we are accustomed to deal with amongst the higher plants and animals, is not altogether illusory amongst such lowly organised forms of life as the bacteria. No biologist nowadays believes in the absolute fixity of species … but there are two circumstances which here render the problem of specificity even more difficult of solution. The bacteriologist is deprived of the test of mutual fertility or sterility, so valuable in determining specific limits amongst organisms in which sexual reproduction prevails. Further, the extreme rapidity with which generation succeeds generation amongst bacteria offers to the forces of variation and natural selection a field for their operation wholly unparalleled amongst higher forms of life.
'The Evolution of the Streptococci', The Lancet, 1906, 2, 1415-6.

No one who has seen a baby sinking back satiated from the breast and falling asleep with flushed cheeks and a blissful smile can escape the reflection that this picture persists as a prototype of the expression of sexual satisfaction in later life.
Three Essays on Sexuality: Infantile Sexuality (1905), In James Strachey (ed.), The Standard Edition of the Complete Psychological Works of Sigmund Freud (1953), Vol 7, 182.

On the one hand, then, in the reproductive functions proper—menstruation, defloration, pregnancy and parturition—woman is biologically doomed to suffer. Nature seems to have no hesitation in administering to her strong doses of pain, and she can do nothing but submit passively to the regimen prescribed. On the other hand, as regards sexual attraction, which is necessary for the act of impregnation, and as regards the erotic pleasures experienced during the act itself, the woman may be on an equal footing with the man.
'Passivity, Masochism and Femininity', Journal of Psychoanalysis, 1935, 16, 327.

Plants are hunters, murderers, sexual deceivers, empire builders. All sorts of things.
Answering the reporter’s question whether he thought plants are passive life forms, doing not much of anything but growing. In Nadine Brozan, 'Chronicle: Bringing the Secret Life of Plants to Light', New York Times (9 Oct 1995), Sec. A, 13. Attenborough was on a lecture tour about The Private Life of Plants, the title of his book and a six-part BBC TV series.

Sexual instinct—as emotion, idea, and impulse—is a function of the cerebral cortex. Thus far no definite region of the cortex has been proved to be exclusively the seat of sexual sensations and impulses.
Psychopathia Sexualis: With Special Reference to Contrary Sexual Instinct: A Medico-Legal Study (1886), trans. Charles Gilbert Chaddock (1892), 24.

So-called psychoanalysis is the occupation of lustful rationalists who trace everything in the world to sexual causes—with the exception of their occupation.
Trans. by Harry Zohn, originally published in Beim Wort genommen (1955). Half-Truths and One-and-a-Half Truths, University of Chicago Press (1990)

The excremental is all too intimately and inseparably bound up with the sexual; the position of the genitals—inter urinas et faeces—remains the decisive and unchangeable factor. One might say here, varying a well-known saying of the great Napoleon: 'Anatomy is destiny'.
On the Universal Tendency to Debasement in the Sphere of Love (Contributions to the Psychology of Love) (1912), In James Strachey (ed.), The Standard Edition of the Complete Psychological Works of Sigmund Freud (1957), Vol 11, 189.

The greatest scandal of the century in American psychiatry … is the growing mania among thousands of inept therapists, family counselors, and social workers for arousing false memories of childhood sexual abuse.
In 'Notes of a Fringe-Watcher: The Tragedies of False Memories', Skeptical Inquirer (Fall 1994), 18, 464.

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.
Sexual Behavior in the Human Male (1948), 545.

The modesty of women, which, in its most primitive form among animals, is based on sexual periodicity, is, with that periodicity, an essential condition of courtship.
Psychology of Sex (1933), 30.
Science quotes on:  |  Animal (651)  |  Condition (362)  |  Essential (210)  |  Form (976)  |  Modesty (18)  |  Most (1728)  |  Periodicity (6)  |  Primitive (79)  |  Sex (68)

The symptoms of neurosis, as we have learnt, are essentially substitute gratifications for unfulfilled sexual wishes.
In Sigmund Freud and Joan Riviere (trans.), Civilization and Its Discontents (1930, 1994), 65.
Science quotes on:  |  Essential (210)  |  Gratification (22)  |  Neurosis (9)  |  Psychology (166)  |  Substitute (47)  |  Symptom (38)  |  Unfulfilled (3)  |  Wish (216)

The weakness of men in comparison with women lies in the great intensity of their sexual desires. Man becomes dependent upon woman, and the more, the weaker and more sensual he becomes; and this just in proportion as he becomes neuropathic.
Psychopathia Sexualis: With Special Reference to Contrary Sexual Instinct: A Medico-Legal Study (1886), trans. Charles Gilbert Chaddock (1892), 14.
Science quotes on:  |  Become (821)  |  Comparison (108)  |  Desire (212)  |  Great (1610)  |  Intensity (34)  |  Lie (370)  |  Man (2252)  |  Men (20)  |  More (2558)  |  Proportion (140)  |  Sex (68)  |  Weakness (50)  |  Woman (160)  |  Women (9)

Too early and perverse sexual satisfaction injures not merely the mind, but also the body; inasmuch as it induces neuroses of the sexual apparatus (irritable weakness of the centres governing erection and ejaculation; defective pleasurable feeling in coitus), while, at the same time, it maintains the imagination and libido in continuous excitement.
Psychopathia Sexualis: With Special Reference to Contrary Sexual Instinct: A Medico-Legal Study (1886), trans. Charles Gilbert Chaddock (1892), 189.

We know less about the sexual life of little girls than of boys. But we need not feel ashamed of this distinction; after all, the sexual life of adult women is a 'dark continent' for psychology.
The Question of Lay Analysis (1926), in James Strachey (ed.), The Standard Edition of the Complete Psychological Works of Sigmund Freud (1959), Vol. 20, 212.
Science quotes on:  |  Boy (100)  |  Continent (79)  |  Dark (145)  |  Distinction (72)  |  Feel (371)  |  Girl (38)  |  Know (1538)  |  Life (1870)  |  Little (717)  |  Psychology (166)  |  Sexuality (11)

When I listen to a soprano sing a Handel aria with an astonishing coloratura from that particular larynx, I say to myself, there has to be a biological reason that was useful at some stage. The larynx of a human being did not evolve without having some function. And the only function I can see is sexual attraction.
From 'Interview: Of Mind and Matter: David Attenborough Meets Richard Dawkins', The Guardian (11 Sep 2010).
Science quotes on:  |  Answer (389)  |  Astonish (39)  |  Attraction (61)  |  Biology (232)  |  Evolution (635)  |  Function (235)  |  Human Being (185)  |  Listen (81)  |  Particular (80)  |  Reason (766)  |  Sing (29)  |  Stage (152)  |  Useful (260)

When I was a boy, I could cycle out of town and be in fields in ten minutes. I knew where the birds’ nests and badger setts were. Now children’s mothers would tell them they need someone to go with them, to make sure they weren’t molested by a sexual deviant.
Commenting on today’s increased anxiety with health and safety culture. As reported by Adam Lusher in 'Sir David Attenborough', Daily Mail (28 Feb 2014).
Science quotes on:  |  Badger (2)  |  Bicycle (10)  |  Bird (163)  |  Boy (100)  |  Child (333)  |  Children (201)  |  Cycle (42)  |  Field (378)  |  Know (1538)  |  Minute (129)  |  Mother (116)  |  Nest (26)  |  Safety (58)  |  Tell (344)  |  Town (30)

While up to this time contrary sexual instinct has had but an anthropological, clinical, and forensic interest for science, now, as a result of the latest investigations, there is some thought of therapy in this incurable condition, which so heavily burdens its victims, socially, morally, and mentally. A preparatory step for the application of therapeutic measures is the exact differentiation of the acquired from the congenital cases; and among the latter again, the assignment of the concrete case to its proper position in the categories that have been established empirically.
Psychopathia Sexualis: With Special Reference to Contrary Sexual Instinct: A Medico-Legal Study (1886), trans. Charles Gilbert Chaddock (1892), 319.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
