““Wikipedia can be a surprisingly good gauge of situations like this. To some extent, it tracks the pulse of our current state of public information. As of this writing,2 the Wikipedia entry for “love” describes exactly the choice I have in mind: “Biological models of love tend to see it as a mammalian drive, similar to hunger or thirst. Psychology sees love as more of a social and cultural phenomenon. Certainly love is influenced by hormones … and how people think and behave in love is influenced by their conceptions of love.””
