The distinction between subjectivity and objectivity is a basic idea of philosophy, particularly epistemology and metaphysics. It is often related to discussions of consciousness, agency, personhood, philosophy of mind, philosophy of language, reality, truth, and communication.

• Something is subjective if it is dependent on a mind. If a claim is true exclusively when considering the claim from the viewpoint of a sentient being, it is subjectively true. For example, one person may consider the weather to be pleasantly warm, and another person may consider the same weather to be too hot; both views are subjective. The word subjectivity comes from subject in a philosophical sense, meaning an individual who possesses unique conscious experiences, such as perspectives, feelings, beliefs, and desires, or who (consciously) acts upon or wields power over some other entity.
• Something is objective if it can be confirmed independently of a mind. If a claim is true even when considering it outside the viewpoint of a sentient being, then it is labelled objectively true. Scientific objectivity is practicing science while intentionally reducing partiality, biases, or external influences. Moral objectivity is the concept of moral or ethical codes being compared to one another through a set of universal facts or a universal perspective and not through differing conflicting perspectives. Journalistic objectivity is the reporting of facts and news with minimal personal bias or in an impartial or politically neutral manner.
