St. Thomas Aquinas was one of the most brilliant philosopher-theologians in the history of the Catholic Church. His definition of truth, which is still valid today, is that truth is the conformity/agreement of the mind to reality. This means that objective truth lies outside of us, outside the human mind. The human mind discovers/learns/ finds truth; it does not invent it.

What arises in our own minds is opinion which may or may conform well to reality. It is the role of the human mind to seek objective truth. That is how God designed the mind. Some times it takes eons to discover a truth or set of truths. Ex. The laws of aerodynamics have existed probably since the beginning of time, but they were discovered only in the last century.

We live in a world in which too many believe that truth is manufactured by the human mind, that man does not discover truth, but determines it. This attitude is far more prevalent is matters of the spiritual and the intellectual spheres like religion, morality, ethics, education, government, etc. In these areas opinion, often the loudest, becomes “truth”.

But truth comes from God and when man dares to usurp that authority, the consequences can be disastrous. Frederick Hegel, a nineteenth century philosopher, when told that his theories did not fit the facts, said,  in effect, that was just too bad for the facts. He was one of the founders of Communism. As a result of this invented “truth,” millions of people were enslaved and worse for almost a century.

The theory of evolution is much in a news today. Honest scientists will admit that evolution is far from a proven theory. About 90-95% of contemporary scientists admit they are materialists and act as thought evolution were a fact.  If it’s not matter, it doesn’t matter.”

Materialism is a philosophy; it is not science, but scientists prefer pretending evolution is a fact because, as Thomas Huxley, an associate of Darwin, said that he liked the idea of evolution because if man were merely a high-grade monkey, he is not responsible for his actions, and, therefore,  he could continue to what do we call sin. In fact,  evolution has long since  passed from the realm of science and has become a quasi religion among many scientists. That’s why there is a kind of frenzy about protecting the theory of evolution against the inroads of logic or fact.

The ACLU is so vehemently anti-Christian that is quite willing to distort and manipulate facts to make the U.S. Constitution say whatever the organization wants it to say. The result has been constantly invented “truth” aimed at the Christian community.

If we do not live in the real world, must then live in a world of whim, fantasy, opinion, subjectivism, etc. Only by living in the real world can we even hope to live a fully human life.

In a world that denies objective truth in matters transcendental and spiritual, and tells us that opinion is a good substitute for truth, we have the words of Christ (Jn 14:5) that He and He alone is the embodiment of truth, that He is the only source of truth.  If we ignore that, we do so at great peril not only to out temporal life, but to our eternal life.

Remember this: an idea  is not true because we say it is or because we believe it is, or because the majority favors it is, an idea is true only if it conforms to objective reality.
