On the Sublime and Beautiful

I have endeavored to make this edition something more full and satisfactory than the first. I have sought with the utmost care, and read with equal attention, everything which has appeared in public against my opinions; I have taken advantage of the candid liberty of my friends; and if by these means I have been better enabled to discover the imperfections of the work, the indulgence it has received, imperfect as it was, furnished me with a new motive to spare no reasonable pains for its improvement.
