It’s all quite simple, although somewhat off the original topic, but I’m sure VoR will agree.
The elements of reason are senses, concepts and logic.
To "follow reason” means to base knowledge on observation, then form concepts according to the actual relationships among concretes and use those concepts according to the rules of logic.
Since each of these three elements is based on reality (or fact) any conclusions reached by a process of reason are objective.
One of the alternatives to reason is skepticism.
The skeptic denies the possibility of any knowledge, claims that man’s means of cognition are inadequate and follows his feelings or beliefs which he says, are the only basis of action in an unknowable world.
Feelings or beliefs are products of ideas only. They are not tools of cognition nor are they a guide to action.
