'male scorpionflies who have a notal organ (clamp) located on the top of their abdomen that, as far as the authors can tell, was designed specifically for rape. This organ is only used to gain sexual access to unwilling female scorpionflies when males have no nuptial gift (hardened salvia or a dead insect). Human males do not have a similar rape organ, but the authors argue that the rape adaptation is found in the male psyche.:
A Natural History of Rape: Biological Bases of Sexual Coercion by Randy Thornhill and Craig T. Palmer
Cambridge, Mass.: The MIT Press, 2000
Do you even appreciate the humor is the quotation?
a.) 'designed' specifically for rape I can't believe that two biological scientists are talking about physical features of scorpionflies being 'designed'. Evolved, meh, maybe.
b.) Human males, do have an organ used in rape, although I doubt that sicentists would agree the the penis is a rape organ. I also loved the mechanical metaphor of 'clamp'.
Biological scientists are operating in dangerous territory when discussing the male psyche. And notice the language 'the c.) authors ARGUE (not claim or prove) that the rape 'adaptation' is found in the male psyche. Two guys working with scorpionflies are talking way outside the area of their expertise when they discuss 'the male psyche'. But then it COULD be about the male psyche of scorpionflies...
d.) 'nuptial gift': OK, so now we're talking about reproductive biology in terms of wedding presents??? We're now in the unscientific realm of metaphor. Are you really going to tell me that you see biologists describing sexual behavior in terms or rape and wedding presents as anything other than metaphor? 'Wait til I get my clamp on you, darlin'...'
e.) I find a great deal of humor in the clause 'as far as the authors can tell'--maybe they can't

an admission of limitations?
f.) You adduce one book; I am going to investigate how it held up in peer review. Where are your other four references?
How do they know that the female scorpionflies are 'unwilling' as opposed to biologically non-receptive? I have a Doberman bitch that snarls and fights off the male when she's not receptive (anestrous), but I don't construe that as unwillingness. I think these guys are operating in metaphorical lala-land.
Volition attributed to a scorpionfly? Maybe because there's no wedding gift? Oh, brother.
But you did make me laugh: I'm going to order the book.

'rape is defined with definitions like these??????.... nothing is defined if multiple definitions are required...'
all of your definitions are legal... not applicable in science.....words like crime, consent, offender, person, unlawful....
a.) I made no claim that multiple definitions are required. I guess what I was trying to do is illustrate that there is a consensus of what rape is by adducing multiple definitions that contain the same or similar differentiae.
A definition consists of the definiendum (the thing to be defined), a discrimen (a first general attempt at classification or categorization, and differentiae (elements that are necessary to make the definition exact. (example: a margarita is a cocktail made with tequila, lime juice and triple sec) What I tried to do is show that rape is defined as human behavior classified as a crime that involves sexual assault by or penetration of an unwilling recipient viewed as an offender/victim relationship.
b.) What logical principle do you know that insists that there be only be one definition of the definiendum, and that multiple definitions invalidate any one definition? Odd...and not true.
3.) socio in this context is social behavior. OK, humorously: so the exercise of the reproductive function of scorpionflies is social. Ah, what the hell...
4.) Your otter example (yes, I am trying to be funny) uses the words intromission and mating are used but never rape. Nothing more to be said there.
There's just one last thing, and then I'll buy you a drink! One of the most distinctive differences between human rape and the sometimes extremely aggressive male reproductive behavior elsewhere in the animal kingdom is that the rapist is NOT committing rape for the continuation of the species--it's exercise of violent sexual domination for the rapist's psychological and physical pleasure against an unwilling victim--it is not a reproductive effort, given that rape can be accomplished with an object or the forcible penetration of other parts of the body than the female vagina. And the rape of a male by another male is certainly not an attempt at reproduction.
