 Even if some of our trust could be rational, one might insist that not all of it could be rational for various reasons. First, if Baier is right that trust is ubiquitous (1986: 234), then we could not possibly subject all of it to rational reflection. We certainly could not reflect on every bit of knowledge we’ve acquired through the testimony of others, such as that the earth is round or Antarctica exists (Webb 1993; E. Fricker 1995; Coady 1992). Second, bioethicists point out that some trust is unavoidable and occurs in the absence of rational reflection (e.g., trust in emergency room nurses and physicians; see Zaner 1991). Lastly, some trust—namely the therapeutic variety—purposefully leaps beyond any evidence of trustworthiness in an effort to engender trustworthiness in the trustee. Is this sort of trust rational? Perhaps not, given that there isn’t sufficient evidence for it.
