truth: truth you can measure (which becomes a fact), and truth you can’t (which is a person’s personal experience and is factual to that person).
Think of the temperature of freezing, a measurable fact and universal truth. Compare that to a religious person’s testimony of the Gospel of Jesus Christ, which is a non-measurable thing based on the person’s personal experience; it is truth for that person or “their truth.”
The former is a universal truth and universal fact, while the latter is truth to that person and a fact to that person.
The world consists of both kinds of truth. One is generally more trustworthy and universal than the other, but non-measurable truth can be equally important for all kinds of reasons.
