Some scholars have noted that Blake's views on "free love" are both qualified and may have undergone shifts and modifications in his late years. Some poems from this period warn of dangers of predatory sexuality such as "The Sick Rose". Magnus Ankarsjö notes that while the hero of "Visions of the Daughters of Albion" is a strong advocate of free love, by the end of the poem she has become more circumspect as her awareness of the dark side of sexuality has grown, crying "Can this be love which drinks another as a sponge drinks water?" Ankarsjö also notes that a major inspiration to Blake, Mary Wollstonecraft, similarly developed more circumspect views of sexual freedom late in life. In light of Blake's aforementioned sense of human 'fallenness' Ankarsjö thinks Blake does "not" fully approve of sensual indulgence merely in defiance of law as exemplified by the female character of Leutha, since in the fallen world of experience all love is enchained. Ankarsjö records Blake as having supported a commune with some sharing of partners, though David Worrall read "The Book of Thel" as a rejection of the proposal to take concubines espoused by some members of the Swedenborgian church.
