In the light of that truth, a reformed intuitionalism might justify itself.
The design argument is available for the slightly bolder philosophy of intuitionalism as well as for empiricist theism.
Kant then has broken away from intuitionalism by substituting one system of necessity for the many necessary truths or given experiences from which intuitionalism takes its start.
Other schools of philosophy pay flying visits to theism; intuitionalism is at home there.
It is a manifest weakness in intuitionalism Evolu- that it finds such difficulty in leaving room for evolu- tionary change.
As a philosophy, intuitionalism leaves the mind in all the embarrassment of an indefinite number of separate startingpoints.
It reasserts them, with resolute loyalty; but if philosophy ought to vindicate, to explain, perhaps incidentally to modify, even, it may be, to purify our primary beliefs, intuitionalism is hardly a philosophy at all.
But intuitionalism claims to allege a higher certainty; everything (or every change) must have a cause - this is not merely actual fact but necessary truth.
Here then characteristically intuitionalism occupies a half-way house between empiricism, with its appeal to real given fact, and idealism, with its appeal to necessity.
Common-sense intuitionalism would deny that man does this, attributing to him immediate knowledge of reality.
