Is there any such thing as an absolute?

In the absence of certainty what is there but (evidence based) estimation of likelihood?Is there any knowledge we can possess which isn't either tautological or "playing probabilities"....? Can you give an example of such? Is there any knowledge that isn't tautological in your view and how certain of such knowledge can we be?

In order to maintain that some approximations are better than others perhaps? Verisimilitude is a reasonably widespread concept in the philosophy of science.Even if you cannot ever achieve truth, even if you cannot know what "truth" is, that doesn't stop some answers being better approximations to it than others.If you are going to talk about "approximations" you need to decide what it is you are approximating...... Right?

My desk is 1.7543698765423410981666 centimeters longMy desk is about a meter and a half long.One of these statements is highly precise but a very poor approximation. The other statement is very approximate but far more accurate.Which of the two statements is the better approximation?Being roughly accurate trumps being precisely wrong.
It's accuracy that we should be aiming for. Without it precision is really rather worthless.

Biblical creationists make highly precise calculations about the age of the Earth. Down to the number of days in some cases.Science tells us an age of the Earth that is nowhere near as precise as that.Which is the better approximation? Only if it is accurate. Being ever more precisely wrong is entirely pointless. Being ever more precise is only of value if combined with a degree of accuracy. More accurate theories are more useful......Edited by Straggler, : No reason given.
