From Milton's L'Allegro
Night Startled by the Lark
Art and science have their origin in mental activity through which imagination gains expression. Preoccupation with physical activity depresses the intellect and the imagination which are vehicles for the spirit. Blake is in entire agreement with Jesus' instruction that our attention be given to seeking the kingdom not to providing for our physical needs. By devoting himself to outpourings of the imagination - art and science - he built the kingdom and found fulfillment in his inner life.
Jerusalem, Plate 77, (E 231)
O ye Religious discountenance every one among
you who shall pretend to despise Art & Science! I call upon you
in the Name of Jesus! What is the Life of Man but Art & Science?
is it Meat & Drink? is not the Body more than Raiment? What is
Mortality but the things relating to the Body, which Dies? What
is Immortality but the things relating to the Spirit, which Lives
Eternally! What is the joy of Heaven but Improvement in the
things of the Spirit? What are the Pains of Hell but Ignorance,
Bodily Lust, Idleness & devastation of the things of the Spirit[?]
 And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin:
 And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these.
 Wherefore, if God so clothe the grass of the field, which to day is, and to morrow is cast into the oven, shall he not much more clothe you, O ye of little faith?
 Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed?
 (For after all these things do the Gentiles seek:) for your heavenly Father knoweth that ye have need of all these things.
 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.
 Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
