Trust and Certainty

Modern Philosophy perhaps takes an alternative tack if Descartes posits Trust, not Certainty, as his criterion.  On that basis, he would begin by finding the Senses to be untrustworthy, eventually arriving at the realization that he cannot mistrust that he mistrusts, from which he can establish his trust in God, and, thereby, in Mathematics, etc. A primary difference between Trust and Certainty is that the former is unambiguously Practical, while the latter is problematically Cognitive, i. e. even if Descartes can show that the act 'I doubt' coincides with the object 'I doubt', it cannot be more than instantaneous, whereas Trust entails temporal continuity.  Likewise, the weakness of Sense Experience is not that it is necessarily false, but that even if on one occasion its objects are what they appear to be, it is only via Trust, i. e. Certainty does not suffice, that that moment can be extended.  So, one alternate course of Modern Philosophy is Pragmatist from the outset.
