"By reflection, . . . I would be understood to mean, that notice which the mind takes of its own operations, and the manner of them, by reason whereof there come to be ideas of these operations in the understanding." (Locke) "This delight grows and improves under thought and reflection." (South) 2. Shining; brightness, as of the sun. 3. That which is produced by reflection.
