The mark of a mature, psychologically healthy mind is indeed the ability to live with uncertainty and ambiguity, but only as much as there really is. Uncertainty is no virtue when the facts are clear, and ambiguity is mere obfuscation when more precise terms are applicable.

Life is full of what-ifs, many of which could easily have been realities, had just a few things been different.

Science works because the phenomenon being described can be relied on to remain the same. Even in quantum physics, where phenomena are changed by observation, the way in which observation interferes is regular and falls within a limited range of possibilities. Human culture, however, has the nasty habit of never staying the same for very long.

Economics is uncertain because its fundamental subject matter is not money but human action. That's why economics is not the dismal science, it's no science at all.

The mark of a mature, psychologically healthy mind is indeed the ability to live with uncertainty and ambiguity, but only as much as there really is. Uncertainty is no virtue when the facts are clear, and ambiguity is mere obfuscation when more precise terms are applicable.

The greatest moral failing is to condemn something as a moral failing: no vice is worse than being judgmental.
