This chapter examines the use of ‘always’ and ‘necessarily’ in De Caelo I.12. From here, it takes ‘necessarily’ and ‘impossible’ as meaning ‘necessarily/impossible in the strongest sense’. Meanwhile, ‘always’ is meant without restriction. Aristotle was not necessarily inconsistent in maintaining B' as a rational position even at a time when he denied one of the assumptions essential to the De Caello proof. The Physics analysis of ‘infinite’ is proof only if ‘always’ and ‘for an infinite time’ are made synonymous.

Keywords: always; necessarily; impossible; Hintikka; infinite time
