[trevyn]

I'm saying that people capable of coherent thought can choose, over time, not to have mood disorders, which is a subtly different point.

I fully recognize that when you're in a depressive state, things seem hopeless and that you feel unable to choose a different state.

My proposition is that in all but the most serious cases, you actually can choose, if you're given the right mental frameworks and sensory inputs.

Of course, the devil is in the details of identifying and providing those frameworks and inputs.
