That they decay means they weren’t truths in the first place. There’s a big terminology problem with this article, with facts being changed, remade, unmade etc. But then why call them facts? Because people think they’re factual? If it turns out they were wrong it means they were wrong, is all. Not that facts have changed.
Cutesy postmodernism bores me. Poetry is something else, and I’ll allow Robert Frost in “Black Cottage” what I won’t the author of this article observe:
“For, dear me, why abandon a belief
Merely because it ceases to be true
Cling to it long enough, and not a doubt
It will turn true again, for so it goes
Most of the change we think we see in life
Is due to truths being in and out of favor”
The original author has made a major mistake in terminology. A fact is something that can be proved; facts don’t change. What he is calling fact is inference, or conclusions drawn from facts. As our knowlege increases, including more facts, the inferences we make from that knowlege can change, sometimes drastically.
Facts are circumstances that are changeable like the wind. Truth (technically with a capital "T") is derived from the Bible, God's Word, and is absolute - Truth never changes. I suppose you could talk about the "truth" about the "facts" but again, the truth aspect focuses on universal, unchanging principles, so interchanging "fact" and "truth" tends to confuse things.
For example, maybe the medical report says I have cancer. That's a fact, Jack. But then God tells me in His Word, the Bible, that "By His [Jesus'] stripes I am healed" (Isaiah 53:5, 1 Peter 2:24). That's the truth.
The circumstances of the medical report and symptoms are subject to change, and often do change. However, the truth of God's Word, that Jesus took all my disease upon Himself, never changes - it is always true no matter what. "Heaven and earth shall pass away, but my words shall not pass away." Matthew 24:35, Mark 13:31, Luke 21:33. And that's the truth.
