Inconsistencies in men are generally testimony to their immaturity.

The quote links steadiness of conduct with moral and emotional adulthood. Cole suggests that when a person’s actions, commitments, or values shift unpredictably, the deeper issue is often immaturity—an incomplete integration of beliefs into habits and responsibilities. Read this way, “inconsistency” is evidence: it reveals a character still being formed, prone to impulse, peer pressure, or short-term desire. The implication is both diagnostic and aspirational: maturity shows itself in reliability, congruence between words and deeds, and the capacity to choose long-term principles over momentary moods.
