My justification for the use of logic is that logic allows us to eliminate (reduce) “erroneous paths” to truth. Thereby allowing us to get as close as it is possible, to the truth. My justification is a conclusion, not an inference, therefore it is not circular.
Why do we use logic?
The logic used to explain miracles of everyday life, thinking logically helps man to question the functioning of everything around us, the logic used to argue and is somehow a thought an idea that influences us for an action we do in our daily lives.
What is logic and why do we need it?
Logic is essentially the study of reasoning or argumentation. We use reason all the time to draw inferences that are useful to us.
How can we use logic in our daily life?
Logic shapes every choice of our daily lives. Logical thinking enables someone to learn and make decisions that affect their way of life. People would all be running around like chickens with their heads hacked off if no one thought sensibly, and nothing would make sense.
