I have no expectations of "logic systems", but I do hope that those who post on discussion boards express themselves clearly and unambiguously. Sometimes I'm disappointed.

Only an entity "outside" of the system can make unfalsifiable claims about the system. e.g God. You've just told me that only claims made "outside the system" can be unfalsifiable. In other words, claims from within the system must all be falsifiable (logically entailed - a biza...

Popper concluded that it is impossible to know that a theory is true based on observations (O); science can tell us only that the theory is false (or that it has yet to be refuted). He concluded that meaningful scientific statements are falsifiable. I have no problem with that at all. So can you te...

Of course you're free to use the word in any way you wish but the fact remains that 'falsifiability' has a very specific meaning in the philosophy of science. Perhaps you can explain this difference to me? When I google for "falsifiability" I end up on the pages which describe my current ...

You're going to cause confusion if you continue to conflate the terms on a philosophy forum. And yet you were perfectly capable of recognising that I mean the same thing by "falsifiability" and "falsification", so I guess your warning of confusion is somewhat unnecessary? You se...

I know you are.

The two terms have quite distinct meanings (particularly in philosophy).

You're going to cause confusion if you continue to conflate the terms on a philosophy forum.

Falsification is about disconfirmation of hypothesis/expectation/prediction.

As I suspected, you're confusing falsifiability (testability) with falsification (disproof).

This objection makes no sense to me. What do you think the word 'falsifiable' means? https://en.wikipedia.org/wiki/Falsifiability Essentially falsifiable means testable. If we substitute 'testable' for 'falsifiable' in your original statement: If a claim is testable in principle then it cannot poss...

Logik wrote: ↑Fri Dec 14, 2018 9:44 amIf a claim is falsifiable in principle then it cannot possibly be a 'true irrespective of what anybody believes or claims to know'!

To believe both at the same time is incoherent nonsense.

This objection makes no sense to me. What do you think the word 'falsifiable' means?

Those activities are not science, and if you think they are, then you don't even have the bare basics down regarding what science is. For one thing, no experiments are involved in such observations, so how is it science? Common sense observations about the world do not involve science. The whole of...
