Tank you both, Approaching Infinity and Jason.
And now, a tough one (at least for me):
Under 1.0. in the Abstract, we can read, right before the explanation of the meaning of Consciouness:
"At any given moment only the Probabilities of any given Truth can be ascertained.
These probabilities, like the Truth they concern, are objective though not quantifiable."
My comment: If the probability can be known with certainty (ascertained), it should be quantifiable, since its expression is a ratio (the ratio of the number of actual occurrences to the total number of possible occurrences). If not, the probability is subjective.
