Lectures on Aesthetics (LA; German: Vorlesungen über die Ästhetik, VÄ) is a compilation of notes from university lectures on aesthetics given by Georg Wilhelm Friedrich Hegel in Heidelberg in 1818 and in Berlin in 1820/21, 1823, 1826 and 1828/29. It was compiled in 1835 by his student Heinrich Gustav Hotho, using Hegel's own hand-written notes and notes his students took during the lectures, but Hotho's work may render some of Hegel's thought more systematic than Hegel's initial presentation.
Hegel's Aesthetics is regarded by many as one of the greatest aesthetic theories to have been produced since Aristotle. Hegel's thesis about the historical dissolution of art has been the subject of much scholarly debate and influenced such thinkers like Theodor W. Adorno, Martin Heidegger, György Lukács, Jacques Derrida and Arthur Danto. Hegel was himself influenced by Johann Joachim Winckelmann, Immanuel Kant, Friedrich Schiller and Friedrich Wilhelm Joseph Schelling. Heidegger calls Hegel's Lectures on Aesthetics "the most comprehensive reflection on the essence of art that the West possesses".
Hegel develops his account of art as a mode of absolute spirit by what of what he terms "the beautiful ideal," which he defines most generally as

This ideal is developed throughout the Lectures accordance Hegel's Logic:
