You need reason and rationalism in everyday life. Say there is someone trying to sale you something illegal, you have to use reasoning and rationalism to decided if you buy the illegal item or not.
Politicians also have to use reasoning and rationalism when they are making laws or when they are deciding on things that could possibly help or hurt the U.S.
Over-all reason and rationalism, is a everyday thing that must be used in order to make good or correct decisions whether it effects just you or other people.
