No, what WLC is saying is that direct personal experience is properly basic.
Eg. If a scientist detects evidence, they are warranted in their belief that their sensory experience of that evidence is worth something. Reality and our sensation of reality is properly basic.
And there is a stronger foundation for believing in the empirical evidence we derive from our senses than there is for accepting the unsupported claim of a skeptic who simply asserts
"no, you didn't experience the Holy Spirit William Lane Craig, you must be delusional or lying"
How does someone else verifiably know what William Lane Craig did or did not experience? They have no 'proper basis' to make assertions about another person reality.
We can test notion of 'properly basic' belief by applying it to someone who says they have never experienced
sensus divinatus.
Imagine if I were to tell an atheist that they must have sensed God.
They insist they haven't. I say yes you have. They say no.
I tell them they must be lying or deliberately suppressing the truth because they don't like the idea. They disagree.
I tell them in that case their God antenna must obviously be broken. (Deluded/mentally ill)
Such an atheist would be right to demand an explanation from me as to how I could possibly know their lived experience (evidence). On what basis can I assert that they HAVE experienced God when their properly basic belief is to trust their real lack of experience of God?
