Dear Reader, due to production systems the following changes could not be made to this article:

In the paragraph immediately preceding the case description (ford-iii), the sentence

Here we explicitly state that Smith’s inference is based only on his belief that Jones owns a Ford, and that this logical inference provides Smith’s only justification for believing that someone in his office owns a Ford (to make things fully precise, we also add a time index).

should be replaced with

Here we explicitly state that Smith’s inference is based only on his belief that Jones owns a Ford (plus the justified background belief that Jones is in his office), and that this logical inference provides Smith’s only justification for believing that someone in his office owns a Ford (to make things fully precise, we also add a time index).Footnote 1

And within the case description (ford-iii), the sentence

From this belief alone, Smith logically infers, at time t, to the justified belief that someone in his office owns a Ford, which provides his only justification for that belief at t.

should be replaced with

From this belief alone (plus the justified background belief that Jones is in his office), Smith logically infers, at time t, to the justified belief that someone in his office owns a Ford, which provides his only justification for that belief at t.Footnote 2
