solipsism

The philosophic system becomes a solipsism, a pure lyric expression of the appetites of human nature.

This theory is also called Subjective Idealism or Solipsism.

I realize now that I may have been falling into the trap of solipsism, “who watches the quad,” et cetera, type of thing.

Thus idealists are wedded to solipsism irrevocably; and it is a happy marriage, only the name of the lady has to be changed.
