The Conscience

The entering wedge for this more concrete way of understanding the dualism was
fashioned by Locke when he made the word 'idea' stand indifferently for thing and
thought, and by Berkeley when he said that what common sense means by realities
is exactly what the philosopher means by ideas. Neither Locke nor Berkeley
thought his truth out into perfect clearness, but it seems to me that the conception I
am defending does little more than consistently carry out the 'pragmatic' method
which they were the first to use.
