Lumpers and Splitters/usage in Various Fields

Famous quotes containing the words usage and/or fields:

    I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.
    —A.J. (Alfred Jules)

    Luxurious Man, to bring his Vice in use,
    Did after him the World seduce:
    And from the fields the Flow’rs and Plants allure,
    Andrew Marvell (1621–1678)
