A DISCOURSE
Delivered to the Students of the Royal Academy on the Distribution of the
Prizes, December 10, 1771, by the President.


Gentlemen,--The value and rank of every art is in proportion to the
mental labour employed in it, or the mental pleasure produced by it. As
this principle is observed or neglected, our profession becomes either a
liberal art or a mechanical trade. In the hands of one man it makes the
highest pretensions, as it is addressed to the noblest faculties, In
those of another it is reduced to a mere matter of ornament, and the
painter has but the humble province of furnishing our apartments with
elegance.

This exertion of mind, which is the only circumstance that truly ennobles
our art, makes the great distinction between the Roman and Venetian
