Someone: I believe X on the basis of evidence.
You: But is it TESTABLE evidence?
S: No, but it is evidence. That’s all I need to justify belief. That is what evidence IS.
Each of us is conscious of the fact we are conscious and we are aware we are aware. The awareness of awareness is not only EVIDENCE we really are aware, but INCORRIGIBLE evidence.
And yet I cannot demonstrate to anyone else I am not an automaton or NPC.
Yet my belief I am conscious is FULLY JUSTIFIED.
3 Therefore it is foolish to tether one’s beliefs to “scientific justification” instead of justification.
2 But science cannot demonstrate, and we should not reject: belief in our own existence, logic, mathematics, perception, etc. etc. etc.
3 ∴ premise 1 is false.
