What Is The Importance Of Logic?

Logic help us to decide our decision. It also make us analyze of what is good argument .
  If you understand logic you may able to adopt and grow  using the same reasoning in times of difficulty.
  Logic is the of learning to think and communicate clearly and coherently.

Logic is an evolutionary advantage that actually predates humans. A cat was put in a room with a bowl of food they did this with two cats. One cat scratched at it then circled it than gave up. The second cat did the same but instead of giving up it jumped on the top of the basket and knocked it over and ate. The cat that ate wouldn't die of starvation in the wild given a similar scenario and would therefor be able to reproduce more and thus be more successful. That is why logic is important.
