 The particular reason why care may be central is that it allows us to grasp how trust and reliance differ. The above suggested that they differ because only trust can be betrayed (or at least let down). But why is that true? Why can trust be betrayed, while mere reliance can only be disappointed? The answer Baier gives is that betrayal is the appropriate response to someone on whom one relied to act out of goodwill, as opposed to ill will, selfishness, or habit bred out of indifference (1986: 234–5; see also Baier 1991). Those who say that trusting could involve relying on people to act instead on motives like ill will or selfishness will have trouble distinguishing between trust and mere reliance.
