Thus Blake's thought and time were fully occupied. Besides the designs for Hayley's ballads, engravings were required for the Cowper _Life_. Butts was to be kept supplied with a fresh picture as fast as Blake could paint it; and his own more secret thought was ruminating over Milton, and his stay at Felpham, and his dreams for the future. These were to take form in his longest poetical works--_Milton_, _The Four Zoas_, and _Jerusalem_; but as they are of extreme importance for understanding Blake, they must be kept over to another chapter.
Blake was thoroughly interested in this work, for he admired Cowper, and considered that his letters were "the very best letters that were ever published." It is necessary to remember his reverence for Cowper, as also for Wesley and Whitefield, because in the poems there are many vigorous attacks made on religion, and some of Blake's modern imitators follow him in the attack. The moderns for the most part are irreligious, but Blake professed to love true religion and true science. What he hated above all things was religion divorced from life and art. Such religion becomes very intense, as in the Pharisees, and when great decisions are called for, as in the trial of Christ, it invariably utters its voice on the wrong side.
Blake's engravings for the Cowper _Life_ were after designs by other artists, the most important being the head of Cowper by Romney. To engrave after another is irksome, and there was further irritation when he found that Hayley was as ready to instruct him how to engrave as to paint miniatures.

Since Hayley could never disguise his inmost thoughts, Blake soon perceived that he intended to keep him strictly to the graver, as he had no opinion of his original works, whether in poetry or design. Blake found relief in painting for Thomas Butts, who was his friend and patron for over thirty years, and to whom he sent exquisite pictures, and some letters priceless for their revelation of the writer.
From these we learn the nature of Blake's spiritual crisis at Felpham.
Miniature portrait painting drove home to him the vast difference between historical designing and portrait painting. Portrait requires nature before the painter's eye, historical designing depends on imagination. Nature and imagination were as antithetical in Blake's eye as nature and grace in the theologian's, and just here he kept as far away from pantheism as he could in his obstinate determination to keep nature and imagination as separate as the sheep and the goats. While agreeing with Blake in keeping them apart, I suppose most of us would say that the finest portrait painting depended on imagination no less than historical designing.
