A subject is a being who has a unique consciousness and/or unique personal experiences, or an entity that has a relationship with another entity that exists outside of itself (called an object). A subject is an observer and an object is a thing observed. This concept is especially important in continental philosophy, where 'the Subject' is a central term in debates over human autonomy and the nature of the self. The sharp distinction between subject and object corresponds to the distinction, in the philosophy of RenÃ© Descartes, between thought and extension. Descartes believed that thought (subjectivity) was the essence of the mind, and that extension (the occupation of space) was the essence of matter.
