 [S]cientific styles of thinking &amp; doing are not good because they find out the truth. They have become part of our standards for what it is, to find out the truth. They establish criteria of truthfulness. … Scientific reason, as manifested in Crombie’s six genres of inquiry, has no foundation. The styles are how we reason in the sciences. To say that these styles of thinking &amp; doing are self-authenticating is to say that they are autonomous: they do not answer to some other, higher, or deeper, standard of truth and reason than their own. To repeat: No foundation. The style does not answer to some external canon of truth independent of itself. (2012: 605; Hacking’s emphasis)
