ABSTRACT
In the last chapter we spoke about the substitution of space-time for space and time, and the effect which this has had in substituting strings of events for ‘things’ conceived as substances. In this chapter we will deal with cause and effect as they appear in the light of modern science. It is at least as difficult to purge our imagination of irrelevances in this matter as in regard to substance. The old-fashioned notion of cause appeared in dynamics as ‘force’. We still speak of forces just as we still speak of the sunrise, but we recognise that this is nothing but a convenient way of speaking, in the one case as in the other.
