"An overweening desire for knowledge brings many distractions and much delusion. Many like to be considered learned and to be praised for their wisdom; how much knowledge there is which adds nothing to the good of the soul! To spend yourself on worldly pursuits which do nothing to further your eternal salvation is unwise.
It is useless to spend much time in talking; only a holy life and a good conscience will ease your mind and satisfy your soul, enabling you to face God with confidence."
(The Imitation of Christ, Book One, chapter two)
