"If this be not done, the Artist may happen to impose on himself by partial reasoning, by a cold consideration of those animated first thoughts which proceeded, not perhaps from caprice or rashness (as he may afterwards conceit) but from the fullness of his mind, enriched with all the copious stores of various inventions that he had ever seen, or had ever passed in his thoughts."
A Discourse Delivered to the Students of the Royal Academy [Discourses on Art]
From 1769 to 1772 Reynolds' lectures were delivered annually, with each discourse published shortly after its delivery. After 1772, the lectures were delivered biennially. The first seven discourses were collected and published together in 1778. In 1797, the first collected edition of all fifteen appeared, with a second edition issued in 1798.
