Is there any way to decrease your courage?

It seems to be easy to gain courage if you suddenly realized and admitted that you are a coward. So, following Aristotelian advice, simply "do acts of courage and become courageous." Imagine that you came to the conclusion that you are foolhardy. What can be done with that?

That’s a nice question.

There is a plausible thought that if you are too fearful you can habituate yourself to be less fearful by exposing yourself to the right kinds of situations (e.g. not too overwhelming). This works well with the progressive move from cowardice to courage.

But as you note, it doesn’t quite work for rashness to courage. With rashness there is an excess of inappropriate action with deficient fear. One could refrain from the rash act, but that wouldn’t necessarily make one less rash because the deficient amount of fear has not been addressed. So this developmental move from rashness to courage would require more, e.g. a purposeful attempt to better appreciate the situation and its risks, or to better understand what is valuable and what matters, etc to provoke more, and appropriate, fear. 

Of course understanding of what courage requires is part of both developmental journeys, but the one from rashness to courage seems to require a different kind of engagement with the orthos logos.

I wonder if the same disanalogy applies to other virtue and vice triads. 

I take it back, it’s not a nice question, it’s a brilliant question.
