"If you follow reason far enough it always leads to conclusions that are contrary to reason"

This quote by Samuel Butler recommends that factor can be a double-edged sword. On one hand, it can be used to make rational choices and pertain to reasonable conclusions. On the other hand, if one follows reason too far, it can result in conclusions that are not rational or sensible. This could be due to the fact that the individual has actually become too focused on the details and has actually forgotten the bigger picture. It could likewise be since the person has become too connected to their own ideas and has stopped working to think about other point of views. Eventually, this quote acts as a tip to utilize reason sensibly and to be available to other points of view.
