Phenomenology is the structural study of consciousness, debatably contested (though firmly maintained in the academic forum) as first discovered in around 1905 by Edmund Husserl, as experienced and expressed in the first-person (or "I") perspective. Deliberation, direction, and intention establish the cornerstone of "experience." This is the principal domain of psychology and neurophysiology. Though phenomenology has lost lost esteem, many theories are tied in with this philosophy.
For instance, "Epistemology" or "Agnoiology," a focus on the self-conscious mind being the most vital element in knowledge, thereby maintaining the same significance in existence, was established in 1856 as the "theory of knowledge" by James Frederick Ferrier. Though related, it is a separate discipline.
Another related theory is found in "Ontology," or "Ontologia," as discovered in 1692 by Jean le Clerc. This is known as the branch of Metaphysics which concerns a systematic account of existence, a logical theory of "reality in the abstract." This is the hierarchical structuring of knowledge as funneled through subcategorization according to the essence of their cognitive qualities.
Metaphysics of the 4th century b.c. by Aristotle, established earlier by far, dealt with the teleological doctrine of causation and first principles along with the branch of speculation in relation of universals to particulars; this certainly set a standard in the foundation of Phenomenology, Ontology, and Epistemology, though these are indeed distinct disciplines.
Phenomenology separates itself from these other related methods of logic, though, by foremost defining overall experience as a product of its intentionality and implied direction. This dimension of conscious experience has separated the scientific study of consciousness from its relation to experience, and diverted from psychology (science of the psyche) and its original objective which necessitated this conception of a "new science" of consciousness studies. This study of Phenomenology has grown out of favor in recent time.
Likely because the conception of Logic and Ethics have altered greatly over time, mostly as of recent, this philosophy in concern to the meanings objects have in our experience has become restricted to our sensory perceptions of hearing and seeing. So Phenomenology has become a lesser used synonym for intent and experience, as well as an antonym for ontology.
