 In Putnam ([1965]), I rejected Bohm’s interpretation for several reasons which no longer seem good to me. Even today, if you look at the Wikipedia encyclopedia on the Web, you will find it said that Bohm’s theory is mathematically inelegant. Happily, I did not give that reason in Putnam ([1965]), but in any case it is not true. The formula for the velocity field is extremely simple: you have the probability current in the theory anyway, and you take the velocity vector to be proportional to the current. There is nothing particularly inelegant about that; if anything, it is remarkably elegant! (2005: 262)
