John Locke Quote

Mark what 'tis his mind aims at in the question, and not what words he expresses it in: and when you have informed and satisfied him in that, you shall see how his thoughts will enlarge themselves, and how by fit answers he may be led on farther than perhaps you could have imagine. For knowledge is grateful to the understanding, as light to the eyes.
