Summary
Schopenhauer argues that the world fundamentally exists in two aspects: as _idea_ for the knowing subject and as _will_. The book's central claim is that what we perceive as the world, including our own bodies, is only an _idea_, an object for the subject. This _idea_ aspect is structured by the forms of knowledge, time and space, and is processed by the understanding, which unites them into the concept of matter and causal action.
However, Schopenhauer asserts that this is not the complete picture. Beyond its existence as _idea_, the world is also, and more profoundly, _will_. He contends that the world as _will_ is the thing-in-itself, and that our immediate, non-perceptual consciousness of our own bodies reveals this aspect. The body, in fact, is presented as the _objectivity_ of our will, meaning it is will made manifest as _idea_. This work distinguishes "philosophical truth" as the recognition that one's body and one's will are one and the same.
Key concepts
- Idea — The world as it is perceived and known by a subject, existing as an object within the forms of time, space, and causality.
- Will — The fundamental, underlying reality of the world, experienced directly as our own volition and the "thing-in-itself."
- Objectivity of will — The concept that the physical body is the manifestation or objectification of the will, presented as an idea.
- Philosophical truth — The specific recognition that one's own body and one's own will are identical.
- Subject — That which knows all things, the condition for all phenomena, and for whom all existing things exist.
- Understanding — The cognitive faculty that processes sensory data, uniting space and time to form perceptions and the idea of matter.
