Confronting the Crisis Within: Acedia and the Psychological Barriers to Ecological Action

Acedia occupies a distinctive place between climate science communication, depth psychology, and contemplative activism. It anticipates later concerns about climate anxiety, ecological grief, and the psychological barriers to collective action. Its argument that numbness can be more dangerous than overt denial remains especially relevant: a society may acknowledge a crisis intellectually while remaining emotionally unable to respond.

The book also complements work such as Joanna Macy and Chris Johnstone’s Active Hope, which similarly emphasizes facing painful truths, honoring grief, seeing with “new eyes,” and moving into action. MacQuarrie’s distinctive contribution is his naming of the inner resistance to that process as acedia.

Acedia: The Darkness Within (and the Darkness of Climate Change) is a thoughtful, humane, and ambitious book. Its central insight—that climate inaction is inseparable from fear, avoidance, and blocked authenticity—is psychologically persuasive and culturally important. While its central concept is broad and its policy prescriptions limited, the book succeeds as a work of psychological and spiritual diagnosis.

Its lasting value lies in its refusal to reduce climate change to an external problem alone. MacQuarrie argues that the crisis outside cannot be adequately addressed without confronting the crisis of avoidance within. For readers willing to sit with discomfort, the book offers not a shortcut around climate despair, but a disciplined path through it toward responsibility, agency, and more authentic action.

It is an important, reflective, and unusually honest contribution to the psychology of climate change, best read as a work of depth psychology and cultural criticism rather than as a technical climate-policy guide. MacQuarrie connects psychotherapy and Wisdom Studies by treating inner healing and ethical action as one continuous process. Psychotherapy supplies the method for recognizing fear, avoidance, and self-protection; Wisdom Studies supplies the larger frame for asking what a healed, mature person—and a mature culture—should do with that awareness.
