I comment on three areas of concern regarding the notion of profundity in Aaron Ben-Ze'ev's The Arc of Love. First, I consider the role of time in the concept of profundity: is a romantic relationship by definition more profound the longer it lasts? Second, I draw a contrast between two conceptions of profundity: in terms of it being measured quantitatively and as being dependent on judgments that cannot be reduced to quantitative measurements. I end with a few brief comments on issues of sexual diversity and polyamory, and their relation to Ben-Ze'ev's views on intimacy and profundity.
