==Sigmund Freud==

[[Sigmund Freud]]'s [[concept]] of the [[drive]] (''Trieb'', ''pulsion'') is central to his theory of [[human]] [[sexuality]].

At first these component drives function anarchically and independently (the '[[polymorphous perversity]]' of [[children]]), but in puberty they become organised and fused together under the primacy of the genital organs.<ref>Freud, 1905d</ref>
