- Piano Concerto No. 1 (Tchaikovsky) (Wikipedia)
The Piano Concerto No. 1 in B♭ minor, Op. 23, was composed by Pyotr Ilyich Tchaikovsky between November 1874 and February 1875. It was revised in 1879 and in 1888. It was first performed on October 25, 1875, in Boston by Hans von Bülow after Tchaikovsky’s desired pianist, Nikolai Rubinstein, criticised the piece. Rubinstein later withdrew his criticism and became a fervent champion of the work. It is one of the most popular of Tchaikovsky’s compositions and among the best known of all piano concerti.

This entry discusses philosophical idealism as a movement chiefly in the eighteenth and nineteenth centuries, although anticipated by certain aspects of seventeenth century philosophy and continuing into the twentieth century.
- Idealism (Wikipedia)
Idealism in philosophy, also known as philosophical idealism or metaphysical idealism, is the set of metaphysical perspectives asserting that, most fundamentally, reality is equivalent to mind, spirit, or consciousness; that reality is entirely a mental construct; or that ideas are the highest form of reality or have the greatest claim to being considered “real”. The radical latter view is often first credited to the Ancient Greek philosopher Plato as part of a theory now known as Platonic idealism. Other than in some Western philosophy, idealism also appears in some Indian philosophy, namely in Vedanta, one of the orthodox schools of Hindu philosophy, and in some streams of Buddhism.
