Thought and reasoning are correct or incorrect in virtue of something independent of the thinker’s beliefs, and even independent of the community of thinkers to which he belongs. We take ourselves to form true beliefs about the world around us, about timeless domains of logic and mathematics, and about the right thing to do. We don’t take these capacities to be infallible, but we think they are often reliable in an objective sense, and that they can give us knowledge. The natural internal stance of human life assumes that there is a real world, that many questions, both factual and practical, have correct answers, and that there are norms of thought which, if we follow them, will tend to lead us toward the correct answers to those questions. It assumes that to follow those norms is to respond correctly to values or reasons that we apprehend. Mathematics, science, and ethics are built on such norms.

If all truth is God’s truth, then truth is to be celebrated wherever it is found—and to be pursued wherever it can be found.

The least initial deviation from the truth is multiplied later a thousandfold.
— Aristotle, quoted in Ten Philosophical Mistakes by Mortimer Adler, p. xiii
What makes a thought true is not that it entered my mind, it’s whether reality is the way the thought says reality is.

To say that a statement or proportion is true, simply means that it corresponds to objective (mind independent) reality.
— Douglas Groothuis, from Are All Religions Created Equal at 8:45
For my part I confess to finding it curious that those who claim that there is no such thing as truth expect me to believe that what they are saying is true! Perhaps I misunderstand them, but they seem to exempt themselves from their general rubric that there is no such thing as truth when they are either speaking to me or writing their books. They turn out to believe in truth after all.

[C.S.] Lewis: Here it is (a definition of truth). If one says of what is that it is, or of what is not that it is not, he speaks the truth; but if one says of what is that it is not, or of what is not that it is, he does not speak the truth.
— Peter Kreeft, from Between Heaven and Hell, p. 27
