Moral disqualification the first step to solving a problem is to recognize it — TheMadFool
It almost comes down to a "chicken and egg" problem, haha. What came first: reason or emotion?
Personally, I would say that emotion comes first.
Let us take the example of a calculator which, by today's standards, is a very basic computer. Nonetheless, it can represent the activities of the human brain. We can put whatever we want into that calculator. We could input millions of sums. But in the end we will only choose 1 sum out of those many many possibilities.
My understanding is that our conscious thought processes work the same way. There are millions of possible thoughts. But only 1 will emerge from the brainy ether. What determines that is an emotion, which is provoked by unconscious thought, which in turn is provoked by an external stimulus.
