Subjectivity in the context of "Jean-Jacques Rousseau"

Dialectic (Ancient Greek: διαλεκτική, romanized: dialektikḗ; German: Dialektik), also known as the dialectical method, refers originally to dialogue between people holding different points of view about a subject but wishing to arrive at the truth through reasoned argument. Dialectic resembles debate, but the concept excludes subjective elements such as emotional appeal and rhetoric; the object is more an eventual and commonly-held truth than the 'winning' of an (often binary) competition. It has its origins in ancient philosophy and continued to be developed in the Middle Ages.

Hegelianism refigured "dialectic" to no longer refer to a literal dialogue. Instead, the term takes on the specialized meaning of development by way of overcoming internal contradictions. Dialectical materialism, a theory advanced by Karl Marx and Friedrich Engels, adapted the Hegelian dialectic into a materialist theory of history. The legacy of Hegelian and Marxian dialectics has been criticized by philosophers, such as Karl Popper and Mario Bunge, who considered it unscientific.

According to the APA Dictionary of Psychology, a feeling is "a self-contained phenomenal experience"; feelings are "subjective, evaluative, and independent of the sensations, thoughts, or images evoking them". The term feeling is closely related to, but not the same as, emotion. Feeling may, for instance, refer to the conscious subjective experience of emotions. The study of subjective experiences is called phenomenology. Psychotherapy generally involves a therapist helping a client understand, articulate, and learn to effectively regulate the client's own feelings, and ultimately to take responsibility for the client's experience of the world. Feelings are sometimes held to be characteristic of embodied consciousness.

The English noun feelings may generally refer to any degree of subjectivity in perception or sensation. However, feelings often refer to an individual sense of well-being (perhaps of wholeness, safety, or being loved). Feelings have a semantic field extending from the individual and spiritual to the social and political. The word feeling may refer to any of a number of psychological characteristics of experience, or even to reflect the entire inner life of the individual (see mood). As self-contained phenomenal experiences, evoked by sensations and perceptions, feelings can strongly influence the character of a person's subjective reality. Feelings can sometimes harbor bias or otherwise distort veridical perception, in particular through projection, wishful thinking, among many other such effects.

Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So in this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world is and how the world would have been without the existence of the important entity. It is often argued that importance claims are context- or domain-dependent. This means that they either explicitly or implicitly assume a certain domain in relation to which something matters. For example, studying for an exam is important in the context of academic success but not in the context of world history. Importance comes in degrees: to be important usually means to matter more within the domain in question than most of the other entities within this domain.

The term "importance" is often used in overlapping ways with various related terms, such as "meaningfulness", "value", and "caring". Theorists frequently try to elucidate these terms by comparing them to show what they have in common and how they differ. A meaningful life is usually also important in some sense. But meaningfulness has additional requirements: life should be guided by the agent's intention and directed at realizing some form of higher purpose. In some contexts, to say that something is important means the same as saying that it is valuable. More generally, however, importance refers not to value itself but to a value difference. This difference may also be negative: some events are important because they have very bad consequences. Importance is often treated as an objective feature in contrast to the subjective attitude of caring about something or ascribing importance to it. Ideally, the two overlap: people subjectively care about objectively important things. Nonetheless, the two may come apart when people care about unimportant things or fail to care about important things. Some theorists distinguish between instrumental importance relative to a specific goal in contrast to a form of importance based on intrinsic or final value. A closely related distinction is between importance relative to someone and absolute or unrestricted importance.

Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00 K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to −273.15 °C on the Celsius scale, −459.67 °F on the Fahrenheit scale, and 0.00 °R on the Rankine scale.

Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because of the uncertainty principle.

A mystical or religious experience, also known as a spiritual experience or sacred experience, is a subjective experience which is interpreted within a religious framework. In a strict sense, "mystical experience" refers specifically to an ecstatic unitive experience, or nonduality, of 'self' and other objects, but more broadly may also refer to non-sensual or unconceptualized sensory awareness or insight, while religious experience may refer to any experience relevant in a religious context. Mysticism entails religious traditions of human transformation aided by various practices and religious experiences.

The concept of mystical or religious experience developed in the 19th century, as a defense against the growing rationalism of western society. William James popularized the notion of distinct religious or mystical experiences in his Varieties of Religious Experience, and influenced the understanding of mysticism as a distinctive experience which supplies knowledge of the transcendental.

In acoustics, loudness is the subjective perception of sound pressure. More formally, it is defined as the "attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud". The relation of physical attributes of sound to perceived loudness consists of physical, physiological and psychological components. The study of apparent loudness is included in the topic of psychoacoustics and employs methods of psychophysics.

In different industries, loudness may have different meanings and different measurement standards. Some definitions, such as ITU-R BS.1770 refer to the relative loudness of different segments of electronically reproduced sounds, such as for broadcasting and cinema. Others, such as ISO 532A (Stevens loudness, measured in sones), ISO 532B (Zwicker loudness), DIN 45631 and ASA/ANSI S3.4, have a more general scope and are often used to characterize loudness of environmental noise. More modern standards, such as Nordtest ACOU112 and ISO/AWI 532-3 (in progress) take into account other components of loudness, such as onset rate, time variation and spectral masking.

Western Marxism is a current of Marxist theory that arose from Western and Central Europe in the aftermath of the 1917 October Revolution in Russia and the ascent of Leninism. The term denotes a loose collection of theorists who advanced an interpretation of Marxism distinct from classical and Orthodox Marxism and the Marxism–Leninism of the Soviet Union.

Less concerned with economic analysis than earlier schools of Marxist thought, Western Marxism placed greater emphasis on the study of the cultural trends of capitalist society, deploying the more philosophical and subjective aspects of Marxism, and incorporating non-Marxist approaches to investigating culture and historical development. Key themes included the influence of Georg Wilhelm Friedrich Hegel on Karl Marx's thought, and the recovery of the "Young Marx," emphasizing his early, humanistic writings.

In business, engineering, and manufacturing, quality – or high quality – has a pragmatic interpretation as the non-inferiority or superiority of something (goods or services); it is also defined as being suitable for the intended purpose (fitness for purpose) while satisfying customer expectations. Quality is a perceptual, conditional, and somewhat subjective attribute and may be understood differently by different people. Consumers may focus on the specification quality of a product/service, or how it compares to competitors in the marketplace. Producers might measure the conformance quality, or degree to which the product/service was produced correctly. Support personnel may measure quality in the degree that a product is reliable, maintainable, or sustainable. In such ways, the subjectivity of quality is rendered objective via operational definitions and measured with metrics such as proxy measures.

In a general manner, quality in business consists of "producing a good or service that conforms [to the specification of the client] the first time, in the right quantity, and at the right time". The product or service should not be lower or higher than the specification (under or overquality). Overquality leads to unnecessary additional production costs.
