Truth-value link realism

Truth-value link realism is a type of philosophy that proposes that there is an underlying reality that all thoughts and ideas must fit into. It suggests that there are certain truths and facts that cannot be changed or ignored, no matter what someone believes or thinks. Basically, this philosophy suggests that all of our thoughts and ideas must fit into a pre-existing reality, and be based on facts and truth rather than only opinion.
