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.

व्यक्तिपरकता (Subjectivity) चेतना, वास्तविकता और सत्य के बोध से सम्बन्धित वह दार्शनिक अवधारणा है जिसमें किसी व्यक्ति या अन्य बोध करने वाले जीव को वास्तविकता वसी प्रतीत होती है जैसे उसके अपने स्वयं के गुणों द्वारा प्रभावित हो। यह वस्तुनिष्ठता के विपरीत होती है जिसमें तथ्य वैश्विक-रूप से सत्य होते हैं और बोध करने वाले व्यक्ति या जीव के भीतरी गुणों पर निर्भर नहीं होते। उदाहरण के लिये कोई व्यक्ति क्रोधित हो तो उसे व्यक्तिपरक रूप से कोई अन्य व्यक्ति शत्रु प्रतीत हो सकता है जबकी वस्तुनिष्ठ सत्य में यह अन्य व्यक्ति मित्र हो।
