Progress in Mathematics and Science has been the result of a shared language — something Philosophy lacks
You know (a lot) less than you think. Or perhaps you know (a lot) more than most Philosophers.
It’s not the contradiction it seems to be.
Intelligent design, ironically, is flawed in its design.
Some things you know as part of your existence, and provide a building block for further knowledge. Yet if these a priori truths exist, why isn’t it obvious what they are? After all, Philosophers still can’t agree what are reasonable axioms for philosophising.
The answer sheds light on why Philosophers don’t agree on anything, and the current limits of Philosophy.
