"The same Apology of the Length of Years in composing this Book may serve also to excuse a Repetition of the same Sentiments which may happen to be found in different Places without the Author's Design; but in other Pages it was intended, so that those Rules for the Conduct of the Understanding which are most necessary, should be set in several Lights, that they might with more Frequency and more Force impress the Soul."
— Watts, Isaac (1674-1748)
