A Thing is rarely
The whole or the only Truth.
Most Things are that way.
It’s useful to break the connection between the idea of fact and the idea of truth. A fact is a datum that stands on its own regardless of opinion, belief or perception.
A truth does reflect the opinion, belief or perception of a person.
It is a fact that most pizzas are round; it is a truth (for me) that sausage pizza is the best pizza. Other people see a different truth (they’re wrong, of course, especially if their truth involves anchovies).
When it comes to the best pizza, truth is opinion; a matter of taste (literally in this case).
But it’s not always so clear where facts leave off and truth becomes opinion.
Consider the classic Left/Right truths about the role of government. Both sides marshal considerable fact to support their truth. In the end, it comes down to worldview.
Sometimes truth follows fact and changes as our knowledge of fact improves.
For a long time, it was true that the sun (and everything else) went around the earth. That seemed to follow fact; anyone could see the sun rise in the morning, move across the sky and set in the evening. You could see it move while you were clearly standing still.
The actual fact of the matter turned out to be different.
It’s tempting to wish it always worked this way; that once we fully understood the fact, we would all share the same truth.
Sometimes that’s the case, but in most of the interesting cases, truth has a lot to do with belief. Even when in full possession of fact, people can see the truth differently.
I think that’s an important aspect of reality. That no matter how well we know the facts, we can always still hold different truths, and these truths are often equally true.
