Phenomenology (from Greek ''phainómenon'' "that which appears" and ''lógos'' "study") is the philosophical study of the structures of experience and consciousness. As a philosophical movement it was founded in the early years of the 20th century by Edmund Husserl and was later expanded upon by a circle of his followers at the universities of Göttingen and Munich in Germany. It then spread to France, the United States, and elsewhere, often in contexts far removed from Husserl's early work. Phenomenology should not be considered as a unitary movement; rather, different authors share a common family resemblance but also with many significant differences. Accordingly, “A unique and final definition of phenomenology is dangerous and perhaps even paradoxical as it lacks a thematic focus. In fact, it is not a doctrine, nor a philosophical school, but rather a style of thought, a method, an open and ever-renewed experience having different results, and this may disorient anyone wishing to define the meaning of phenomenology”.〔Farina, Gabriella (2014) Some reflections on the phenomenological method. Dialogues in Philosophy, Mental and Neuro Sciences, 7(2):50-62.http://www.crossingdialogues.com/Ms-A14-07.htm〕 Phenomenology, in Husserl's conception, is primarily concerned with the systematic reflection on and study of the structures of consciousness and the phenomena that appear in acts of consciousness. This ontology (study of reality) can be clearly differentiated from the Cartesian method of analysis which sees the world as objects, sets of objects, and objects acting and reacting upon one another. Husserl's conception of phenomenology has been criticized and developed not only by himself but also by students, such as Edith Stein and Roman Ingarden, by hermeneutic philosophers, such as Martin Heidegger, by existentialists, such as Nicolai Hartmann, Gabriel Marcel, Maurice Merleau-Ponty, Jean-Paul Sartre, and by other philosophers, such as Max Scheler, Paul Ricoeur, Jean-Luc Marion, Emmanuel Lévinas, and sociologists Alfred Schütz and Eric Voegelin. ==Overview== In its most basic form, phenomenology attempts to create conditions for the objective study of topics usually regarded as subjective: consciousness and the content of conscious experiences such as judgments, perceptions, and emotions. Although phenomenology seeks to be scientific, it does not attempt to study consciousness from the perspective of clinical psychology or neurology. Instead, it seeks through systematic reflection to determine the essential properties and structures of experience. There are several assumptions behind phenomenology that help explain its foundations. First, it rejects the concept of objective research. Phenomenologists prefer grouping assumptions through a process called phenomenological epoche. Second, phenomenology believes that analyzing daily human behavior can provide one with a greater understanding of nature. The third assumption is that persons should be explored. This is because persons can be understood through the unique ways they reflect the society they live in. Fourth, phenomenologists prefer to gather “capta,” or conscious experience, rather than traditional data. Finally, phenomenology is considered to be oriented on discovery, and therefore phenomenologists gather research using methods that are far less restricting than in other sciences.〔Orbe, Mark P. (2009). Phenomenology. In S. Littlejohn, & K. Foss (Eds.), Encyclopedia of communication theory. (pp. 750-752). Thousand Oaks, CA: SAGE Publications, Inc.〕 Husserl derived many important concepts central to phenomenology from the works and lectures of his teachers, the philosophers and psychologists Franz Brentano and Carl Stumpf. An important element of phenomenology that Husserl borrowed from Brentano is intentionality (often described as "aboutness"), the notion that consciousness is always consciousness ''of'' something. The object of consciousness is called the ''intentional object'', and this object is constituted for consciousness in many different ways, through, for instance, perception, memory, retention and protention, signification, etc. Throughout these different intentionalities, though they have different structures and different ways of being "about" the object, an object is still constituted as the identical object; consciousness is directed at the same intentional object in direct perception as it is in the immediately following retention of this object and the eventual remembering of it. Though many of the phenomenological methods involve various reductions, phenomenology is, in essence, anti-reductionistic; the reductions are mere tools to better understand and describe the workings of consciousness, not to reduce any phenomenon to these descriptions. In other words, when a reference is made to a thing's ''essence'' or ''idea'', or when one details the constitution of an identical coherent thing by describing what one "really" sees as being only these sides and aspects, these surfaces, it does not mean that the thing is only and exclusively what is described here: The ultimate goal of these reductions is to understand ''how'' these different aspects are constituted into the actual thing as experienced by the person experiencing it. Phenomenology is a direct reaction to the psychologism and physicalism of Husserl's time. Although previously employed by Hegel in his ''Phenomenology of Spirit'', it was Husserl’s adoption of this term (circa 1900) that propelled it into becoming the designation of a philosophical school. As a philosophical perspective, phenomenology is its method, though the specific meaning of the term varies according to how it is conceived by a given philosopher. As envisioned by Husserl, phenomenology is a method of philosophical inquiry that rejects the rationalist bias that has dominated Western thought since Plato in favor of a method of reflective attentiveness that discloses the individual’s “lived experience.”〔Husserl, Edmund. ''The Crisis of the European Sciences and Transcendental Phenomenology.'' Evanston: Northwestern University Press, 1970, pg. 240.〕 Loosely rooted in an epistemological device, with Sceptic roots, called epoché, Husserl’s method entails the suspension of judgment while relying on the intuitive grasp of knowledge, free of presuppositions and intellectualizing. Sometimes depicted as the “science of experience,” the phenomenological method is rooted in intentionality, Husserl’s theory of consciousness (developed from Brentano). Intentionality represents an alternative to the representational theory of consciousness, which holds that reality cannot be grasped directly because it is available only through perceptions of reality that are representations of it in the mind. Husserl countered that consciousness is not “in” the mind but rather conscious of something other than itself (the intentional object), whether the object is a substance or a figment of imagination (i.e., the real processes associated with and underlying the figment). Hence the phenomenological method relies on the description of phenomena as they are given to consciousness, in their immediacy. According to Maurice Natanson (1973, p. 63), ''“The radicality of the phenomenological method is both continuous and discontinuous with philosophy’s general effort to subject experience to fundamental, critical scrutiny: to take nothing for granted and to show the warranty for what we claim to know.”'' In practice, it entails an unusual combination of discipline and detachment to suspend, or bracket, theoretical explanations and second-hand information while determining one's “naive” experience of the matter. The phenomenological method serves to momentarily erase the world of speculation by returning the subject to his or her primordial experience of the matter, whether the object of inquiry is a feeling, an idea, or a perception. According to Husserl the suspension of belief in what we ordinarily take for granted or infer by conjecture diminishes the power of what we customarily embrace as objective reality. According to Rüdiger Safranski (1998, 72), “(and his followers’ ) great ambition was to disregard anything that had until then been thought or said about consciousness or the world () on the lookout for a new way of letting the things (investigated ) approach them, without covering them up with what they already knew.” Martin Heidegger modified Husserl’s conception of phenomenology because of (what Heidegger perceived as) Husserl's subjectivist tendencies. Whereas Husserl conceived humans as having been constituted by states of consciousness, Heidegger countered that consciousness is peripheral to the primacy of one’s existence (i.e., the mode of being of Dasein), which cannot be reduced to one’s consciousness of it. From this angle, one’s state of mind is an “effect” rather than a determinant of existence, including those aspects of existence that one is not conscious of. By shifting the center of gravity from consciousness (psychology) to existence (ontology), Heidegger altered the subsequent direction of phenomenology. As one consequence of Heidegger’s modification of Husserl’s conception, phenomenology became increasingly relevant to psychoanalysis. Whereas Husserl gave priority to a depiction of consciousness that was fundamentally alien to the psychoanalytic conception of the unconscious, Heidegger offered a way to conceptualize experience that could accommodate those aspects of one’s existence that lie on the periphery of sentient awareness.〔Natanson, M.
