Abstract
By 'scientific theory' I shall mean a core of fundamental assumptions
fleshed out by a suitable array of auxiliary assumptions. Let there be two or
more competing scientific theories in a certain field, thrown up by rival
research programmes in Lakatos's sense. Now consider these two
questions:
(1) Which of these theories should I accept?
(2) Which of these theories should I work on?
They are surely very different questions. The personal pronoun 'I' could be
dropped from question (1), which could be reformulated as 'Which of
these theories should anyone accept as the best one, in the light of the
presently available evidence?' In my (1984) I suggested that the best
theory is the one that best fulfils what I depicted as the optimum aim for
science; and this, I argued, will be the one that is best corroborated. Which
means that we may turn question (1) into:
(1 ') Which of these theories is best corroborated?
