 The trilemma emerges because, given that (3) formulates the concept of knowledge as infallible knowledge, only two of (1), (2), and (3) can be held together: if (1) and (2) are true, then (3) is false (there is fallible knowledge); if (1) and (3) are true, then (2) is false (there is infallible knowledge); and if (2) and (3) are true, then (1) is false (there is no knowledge). Pereda maintains that the solution to the trilemma is not to abandon one of the claims, but to recognize that there is both a strong and a weak sense of the concept of knowledge. Pereda’s view has been criticized by Guillermo Hurtado (1996), who contends that the trilemma results from incorrectly analyzing (2), which should be understood not as the claim that any of our beliefs may turn out to be false, but as the claim that some of our beliefs may turn out to be false.
