Subjectivity in a philosophical context is a concept of truth that depends upon an individual's conscious experience. Generally speaking, a philosophical proposition is considered to have subjective truth when its truth conditions are met only when considering the claim from the viewpoint of a sentient being. Subjectivity has been given various and ambiguous definitions by differing sources as it is not often the focal point of philosophical discourse. However, it is related to ideas of consciousness, agency, personhood, philosophy of mind, reality, and truth. Three common definitions include that subjectivity is the quality or condition of:
The varying definitions of subjectivity are often used together and interchangeably. Additionally, the term is also used informally to deride opinions and feelings that the speaker subjectively believes to be unjustified. The term is most commonly used as an explanation for that which influences, informs, and biases people's judgments about truth or reality; it is the collection of the perceptions, experiences, expectations, and personal or cultural understanding of, and beliefs about, an external phenomenon, that are specific to a subject.
Subjectivity is usually contrasted to the philosophy of objectivity, which is a view of truth or reality that is not dependent on the views of a sentient being. For example, the Earth and the Moon have a certain average distance from each other, and this distance does not depend on the experience of any sentient being, so the distance is an objective fact. Subjectivity and objectivity are usually seen as two directly opposing views; therefore, an understanding of one conccept usually influences that of the other.
In Western philosophy, the idea of subjectivity is thought to have its roots in the works of Descartes and Kant though it could also come from Aristotle's work relating to the soul. The idea of subjectivity is often seen as a peripheral to other philosophical concepts, namely skepticism, individuals and individuality, and existentialism. The questions surrounding subjectivity have to do with whether or not people can escape the subjectivity of their own human existence and whether or not there is an obligation to try to do so. Important thinkers who focused on this area of study include Descartes, Locke, Kant, Hegel, Kierkegaard, Husserl, Foucault, Derrida, Nagel, and Sartre.
Subjectivity was rejected by Foucault and Derrida in favor of constructionism, but Sartre embraced and continued Descartes' work in the subject by emphasizing subjectivity in phenomenology. Sartre believed that, even within the material force of human society, the ego was an essentially transcendent being—posited, for instance, in his opus Being and Nothingness through his arguments about the 'being-for-others' and the 'for-itself' (i.e., an objective and subjective human being).
The innermost core of subjectivity resides in a unique act of what Fichte called “self-positing”, where each subject is a point of absolute autonomy, which means that it cannot be reduced to a moment in the network of causes and effects.
One way that subjectivity has been conceptualized by philosophers such as Kierkegaard is in the context of religion. Religious beliefs can vary quite extremely from person to person, but people often think that whatever they believe is the truth. Subjectivity as seen by Descartes and Sartre was a matter of what was dependent on consciousness, so, because religious beliefs require the presence of a consciousness that can believe, they must be subjective. This is in contrast to what has been proven by pure logic or hard sciences, which does not depend on the perception of people, and is therefore considered objective. Subjectivity is what relies on personal perception regardless of what is proven or objective.
Many philosophical arguments within this area of study have to do with moving from subjective thoughts to objective thoughts with many different methods employed to get from one to the other along with a variety of conclusions reached. This is exemplified by Descartes deductions that move from reliance on subjectivity to somewhat of a reliance on God for objectivity. Foucault and Derrida denied the idea of subjectivity in favor of their ideas of constructs in order to account for differences in human thought. Instead of focusing on the idea of consciousness and self-consciousness shaping the way humans perceive the world, these thinkers would argue that it is instead the world that shapes humans, so they would see religion less as a belief and more as a cultural construction.
Others like Husserl and Sartre followed the phenomenological approach. This approach focused on the distinct separation of the human mind and the physical world, where the mind is subjective because it can take liberties like imagination and self-awareness where religion might be examined regardless of any kind of subjectivity. The philosophical conversation around subjectivity remains one that struggles with the epistemological question of what is real, what is made up, and what it would mean to be separated completely from subjectivity.
Subjectivity is an inherently social mode that comes about through innumerable interactions within society. As much as subjectivity is a process of individuation, it is equally a process of socialization, the individual never being isolated in a self-contained environment, but endlessly engaging in interaction with the surrounding world. Culture is a living totality of the subjectivity of any given society constantly undergoing transformation. Subjectivity is both shaped by it and shapes it in turn, but also by other things like the economy, political institutions, communities, as well as the natural world.
Though the boundaries of societies and their cultures are indefinable and arbitrary, the subjectivity inherent in each one is palatable and can be recognized as distinct from others. Subjectivity is in part a particular experience or organization of reality, which includes how one views and interacts with humanity, objects, consciousness, and nature, so the difference between different cultures brings about an alternate experience of existence that forms life in a different manner. A common effect on an individual of this disjunction between subjectivities is culture shock, where the subjectivity of the other culture is considered alien and possibly incomprehensible or even hostile.
Political subjectivity is an emerging concept in social sciences and humanities. Political subjectivity is a reference to the deep embeddedness of subjectivity in the socially intertwined systems of power and meaning. "Politicality", writes Sadeq Rahimi in Meaning, Madness and Political Subjectivity, "is not an added aspect of the subject, but indeed the mode of being of the subject, that is, precisely what the subject is."
