Reason, this word is a major thought process we use it every day sometimes not even realizing it. It is the justification in our judgement and it its that process we are born with and it varies from person to person but will all have it.
We can build upon it with a lifetime of experiences. Reason helps us make those decisions that are sometimes difficult. Our justice system is base on a reasonable doubt. Again, we see how important reason is in our daily life. Does this make sense? a question we often ask ourselves in the course of any day. Reason is our process of what is right or wrong.
