Ineffectual Foundations: Reply to Gwiazda

In an earlier paper I argued that there are cases in which an infinite probabilistic chain can be completed (Peijnenburg 2007). According to Jeremy Gwiazda, however, I have merely shown that the chain in question can be computed, not that it can be completed (Gwiazda 2010). Gwiazda thereby discriminates between two terms that I used as synonyms. In the present paper I discuss to what extent computability and completability can be meaningfully distinguished.
