"Napier, the explorer of the secrets of nature, passed among his countrymen for a trafficker with Satan. Even to-day a certain mystery surrounds the figure of the Laird of Merchiston. ...In Scotland, as in other countries, the universities were exclusive centres of intellectual activity, and the studies at the universities were under the sole dominion of the Church, which naturally laid its ban on investigations that might imperil its own teaching. By his isolation Napier is thus wrapped in a certain mystery, and the mystery is deepened by the fact that we know so little of him, and what we know is at times strangely incongruous with the main preoccupations of his life."
