Saying that he has "at last arrived at Jesus" (for Jesus College, Cambridge) and reflecting on how much has happened since he was last there: "My God! how tumultuous are the movements of my Heart -- Since I quitted this room what and how important Events have been evolved! America! Southey! Miss Fricker! Yes -- Southey -- you are right -- Even Love is the creature of strong Motive -- I certainly love her. I think of her incessantly & with unspeakable tenderness -- with that inward melting away of Soul that symptomatizes it"; writing of his enthusiasm for Pantisocracy: "My head, my heart are all alive -- I have drawn up my arguments in battle array -- they shall have the Tactician Excellence of the Mathematician with the Enthusiasm of the Poet -- The Head shall be the Mass -- the Heart the fiery Spirit, that fills, informs, and agitates the whole"; responding to the news that Shadrach ("Shad") Weekes, Southey's aunt's servant, will join the scheme: "Shad goes with us. He is my Brother!"; writing of how much he longs to be with Southey and adding "Make Edith my Sister -- Surely, Southey! we shall be frendotatoi meta frendous. Most friendly where all are friends"; telling him that "Brookes & Berdmore" have spread the word about Pantisocracy "in mangled forms" at Cambridge; reporting the reaction of one Caldwell who told him that "the Strength of my Imagination had intoxicated my Reason -- and that the acuteness of my Reason had given a directing Influence to my Imagination"; writing that he likes Southey's sonnets "exceedingly," suggesting various changes and commenting on discord in poetry ("Discord for Discord's sake is rather too licentious"); praising specific sonnets; introducing a poem of his own by saying first how ashamed of it he feels and then how delighted he is "to feel you superior to me in Genius as in Virtue"; including a sonnet beginning "No more my Visionary Soul shall dwell"; mentioning exchanging letters with Robert Allen and adding "Perhaps you would like two Sonnets I have written to my Sally"; promising to write "a huge big Letter next week," listing the things he has to do before then, and ending the letter "God love you --."
