In William Faulkner's "Light in August," the quote reflects a deep concern about racial and social divisions. It questions when men will overcome their inherent biases and animosities rooted in their differing backgrounds and identities. The text suggests that such conflicts can be traced back to bloodlines and societal constructs, highlighting the enduring nature of prejudice.

This poignant inquiry invites readers to reflect on the persistence of hatred among people who are biologically or culturally different. It implies that reconciliation and understanding are needed for unity, yet it criticizes the ongoing struggle to achieve this harmony in a divided society.
