Doesn't this first quote contradict the second? The temperature of an object is measurable and objective and is defined as the average kinetic energy of the molecules of the substance/material. That is not subjective or relative to the surrounding objects.
Why is this not provable to be objective in the 2nd quote but in the 1st "Temperature is among them" when referring to objective truths?

Because even if you determine that the temperature of X is Y, you still can't prove that X exists beyond your mind.
If you accept that the object is there, regardless of the availability of proof, you can get as far as proving the object has a temperature. But you will never be able to determine if the object is hot or cold, because hot and cold are always subjective to what you're measuring it against.
