Munger argues that reality often involves many interacting factors, and that useful thinking must accommodate this complexity rather than ignore it. When several causes influence one another, simple explanations may be insufficient. The task is therefore to build an understanding gradually, while remaining attentive to how different elements affect the whole.

His reference to Darwin emphasises a method of patient, evidence-based inquiry. Rather than expecting immediate mastery, Munger recommends proceeding step by step with curiosity and persistence. This approach allows understanding to accumulate over time and makes complicated subjects more manageable.

More broadly, the quote presents intellectual progress as the result of disciplined engagement with complexity. Munger’s point is not that every problem can be reduced to an easy formula, but that sustained observation and careful reasoning can substantially improve a person’s ability to deal with difficult, interconnected questions.
