Love implies anger. The man who is angered by nothing cares about nothing.

Abbey links anger to attachment: if you genuinely love people, places, or principles, you will sometimes feel anger when they are harmed, betrayed, or degraded. The second sentence sharpens the claim into a moral diagnosis—total placidity can signal not enlightenment but indifference. In Abbey’s worldview (shaped by environmental conflict and political dissent), anger is not automatically a vice; it can be evidence of care and a catalyst for resistance. The quote therefore defends “righteous anger” as an emotional proof of commitment, while warning that the absence of anger may reflect a lack of values worth defending.
