Whether seduction should be reckoned a species of lust?

Objections

Objection 1 : It would seem that seduction should not be reckoned a species of lust. For seduction denotes the unlawful violation of a virgin, according to the Decretals (XXXVI, qu. 1) [*Append. Grat. ad can. Lex illa]. But this may occur between an unmarried man and an unmarried woman, which pertains to fornication. Therefore seduction should not be reckoned a species of lust, distinct from fornication.
Objection 2 : Further, Ambrose says (De Patriarch. [*De Abraham i, 4]): "Let no man be deluded by human laws: all seduction is adultery." Now a species is not contained under another that is differentiated in opposition to it. Therefore since adultery is a species of lust, it seems that seduction should not be reckoned a species of lust.
Objection 3 : Further, to do a person an injury would seem to pertain to injustice rather than to lust. Now the seducer does an injury to another, namely the violated maiden's father, who "can take the injury as personal to himself" [*Gratian, ad can. Lex illa], and sue the seducer for damages. Therefore seduction should not be reckoned a species of lust.
