But letting this pass we will only note a
strange illusion characteristic of the modern mind that consists in
introducing science, especially experimental science, into areas
where it does not belong, and the belief that the competence of science
extends to everything. Moderns, intoxicated with the developments
they have achieved in this very particular domain, and having
given themselves so exclusively to this domain that they can no
longer see anything outside it, have naturally come to misconceive
the limits within which experimentation is valid and beyond which
it can yield nothing. We speak here of experimentation in its most
general sense and with no restrictions; obviously, these limits are
still narrower if one takes into consideration only the few modalities
accepted and used by ordinary researchers.
