 Schleiermacher tended to be quite self-deprecating about his sensitivity to and knowledge of art, and hence about his aptitude for aesthetics (e.g., in On Religion and the Soliloquies, where he is clearly rather in awe of the greater talent and expertise in this area that such romantic friends as the Schlegel brothers enjoyed), and accordingly tended to shy away from discussing the subject in detail in his earlier work. However, he did eventually bring himself to confront the subject systematically, namely, in his lectures on aesthetics (first delivered in 1819, and then again in 1825 and 1832–3).
