Quote by Robert A. Heinlein
Theology is never any help; it is searching in a dark cellar at midnight for a black cat that isn't there. Theologians can persuade themselves of anything.
Summary
This quote suggests that theology, the study and reasoning about religious beliefs, is fruitless and unhelpful. The metaphor of searching for a black cat in a dark cellar at midnight implies that theology is a futile and impossible task. It also implies that theologians, due to their subjective persuasion, can convince themselves of anything, regardless of whether it is based on tangible evidence or not. Thus, the quote criticizes the subjective nature of theology and questions its ability to provide concrete answers or solutions.
