> Truth in pure mathematics doesn’t really have any meaning, because you simply invent the rules
Yes, I was saying that you can view mathematics like that. Not everyone does though, so I question that it necessarily is as you say.
I’m further saying that science is not simply belief or faith based, because otherwise all its achievement would look like one big miracle. And that seems contrary to the claim that it would be faith based. Without first philosophy and a logico-metaphysical “foundation”, whatever that could be, to whoch the trilemma could be applied. I think the very idea of something epistemically stronger than practical success that will prove science right is a flawed idea from the outset - what will prove it right? But please try to apply the trilemma - I would be interested. I often learn surprising new things here.
If you read my reply above you will find that I said that primitives are not axioms. These are the things axioms talk about, sometimes also referred to as atoms. But you may refer to them by no matter which word you like if you make it clear. Important is only that we understand reach other, though we will likely not agree. It’s a complex topic, and this medium is not necessarily made for that.
And lastly, my point about the presentation of the trilemma still stands. I did not quote the full sentence to not make this too long, not to make a cheap point against a straw man.
The trilemma is a practical hammer that can be used against first philosophy that tries to prove how everything is from the armchair. But make it a first philosophy itself, and it becomes self defeating.
The natural sciences are, put simply, the study of the natural world via experimentation and the collection of empirical evidence. However none of the empirical evidence you might collect (or any other type of evidence for that matter), can survive the scrutiny of the trilemma. You cannot prove that a chair exists, or an apple, or a pen without relying on circular reasoning, an infinite regression of reasoning, or by inventing some axiomatic foundation. I’m not aware of any scientific knowledge that’s capable of circumventing this trilemma, as you put it.
You might think it’s sensible to believe that apples exist, and that the world you perceive around you is real, but this is strictly a faith based position, no matter how perfectly obvious it might seem to you.
Thanks for your clarification. I really enjoy your arguments.
I reply that I find the idea of from first principles proving the existence of something, e.g. an apple a weird notion. What is the justification of asking for it? That is a rationalistic-philosophic concept I can only chuckle at. What about the human information-processing tract is so special that this would help anything? I completely agree that the trilemma helps against these attempts.
I do not agree that it is a useful or meaningful practice.
I’m not setting out to prove something this way.
I’m saying: you have projects and plans that you want to be successful. Truth found by the scientific method has in general a track record of being repeatably found again, and thus will help you. Religion, philosophy, astrology ideology does not have that track record. That’s what makes science unique and points to that it has found some truths. Otherwise it’s track record would be miraculous.
I’m also saying this is as good as it gets, precisely because of the trilemma.
To try to make myself clear: I’m thinking that this practice of proving from first principles would need to be shown to do anything useful, before I‘ll look into it. I think it’s a failed idea, though I believed it long. It’s often taken for granted, but it’s highly questionable.
