"As the mind does not act till it is rouzed into action by external objects; so when it does act, it acts conformably to the suggestions it receives from these impressions, and takes with its first ideas the hints how to multiply, and improve them."
— St John, Henry, styled first Viscount Bolingbroke (1678-1751)
