A small sample to wet your appetite:
As directly as possible, Idealism is that philosophy that affirms the reality of the Idea. The point is not that any account of reality must be from the standpoint of the Idea, of the Ideal, or that the conceptual is insuperable, as for example McDowell has it; but rather that reality is incompletely furnished unless the Idea is included in it. Idealism is therefore eliminative just when the Idea is accounted the species of which other entities – usually nature or matter, but also appearances – are genera. Nothing in this case is or can be on the far side of the concept. This is eliminative in that it doesn’t allow that the Idea be the Idea while nature be nature; rather the one must become an instance of the other, and the problem is exactly the same whether posed from the perspective of eliminative idealism or eliminative materialism. Idealism, when not eliminative, it seems to me – and I am particularly fond of pointing to some of its less read exemplars, such as Bosanquet or Pringle-Pattison – does not seek to account for one thing in terms of another, but for each thing exactly as it is. Such a view is evident in the fact that, for example, Plato’s auto kath’auto has less to do with Kant’s Ding an sich than with a simpler “itself by itself”: it is a causal account of subjectivityindependent of consciousness, or the “it-attractor” by which whatever becomes becomes what it is.
