We tend to believe that human thought is consciousness and that our emotions can be separated from these thoughts.
This isn’t true.
Our thoughts lead to emotion and emotion leads to thoughts.
Our brains are also wired to try to make sense of the world by assigning value to auspicious and trivial events, creating expectations. Cause and effect. These expectations are what drive emotion.
The result, of course, is that we end up using logic and sound reasoning to justify the decisions we have already made. Basically, we seek re-assurance so that we can make ourselves feel better.
