"The scene of the mind, like a moving picture, must be governed with attention, that it may bring into our view the images we want, and as we want them. Otherwise ideas that are foreign to our actual train of thinking will frequently rush into our thoughts, and become objects of them whether we will or no."
— St John, Henry, styled first Viscount Bolingbroke (1678-1751)
