object

Definition: An object is a technical term in modern philosophy often used in contrast to the term "subject". A "subject" is an observer and an "object" is a thing observed.

For modern philosophers like Descartes, consciousness is a state of cognition that includes the subject—which can never be doubted as only it can be the one who doubts–—and some object(s) that may be considered as not having real or full existence or value independent of the subject who observes it.

Metaphysical frameworks also differ in whether they consider objects exist independently of their properties and, if so, in what way.
