Adds Rodriguez, “A lot of young people talk to me about what they want to do, and it’s a completely different ethos. It’s like you want to make something out of something, not make something out of nothing. The Margiela era was to make something out of nothing. That’s what he did.”

Epistemology (/ɪˌpɪstəˈmɒlədʒi/ (listen); from Ancient Greek ἐπιστήμη (epistḗmē) 'knowledge', and -logy), or the theory of knowledge, is the branch of philosophy concerned with knowledge. Epistemology is considered a major subfield of philosophy, along with other major subfields such as ethics, logic, and metaphysics.^[1]

Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in epistemology are generally clustered around four core areas:

1. The philosophical analysis of the nature of knowledge and the conditions required for a belief to constitute knowledge, such as truth and justification
2. Potential sources of knowledge and justified belief, such as perception, reason, memory, and testimony
3. The structure of a body of knowledge or justified belief, including whether all justified beliefs must be derived from justified foundational beliefs or whether justification requires only a coherent set of beliefs
4. Philosophical skepticism, which questions the possibility of knowledge, and related problems, such as whether skepticism poses a threat to our ordinary knowledge claims and whether it is possible to refute skeptical arguments

In these debates and others, epistemology aims to answer questions such as "What do we know?", "What does it mean to say that we know something?", "What makes justified beliefs justified?", and "How do we know that we know?".

In metaphysics, ontology is the philosophical study of being, as well as related concepts such as existence, becoming, and reality.

Ontology addresses questions of how entities are grouped into categories and which of these entities exist on the most fundamental level. Ontologists often try to determine what the categories or highest kinds are and how they form a system of categories that encompasses classification of all entities. Commonly proposed categories include substances, properties, relations, states of affairs and events. These categories are characterized by fundamental ontological concepts, including particularity and universality, abstractness and concreteness, or possibility and necessity. Of special interest is the concept of ontological dependence, which determines whether the entities of a category exist on the most fundamental level. Disagreements within ontology are often about whether entities belonging to a certain category exist and, if so, how they are related to other entities.

When used as a countable noun, the words ontology and ontologies refer not to the science of being but to theories within the science of being. Ontological theories can be divided into various types according to their theoretical commitments. Monocategorical ontologies hold that there is only one basic category, but polycategorical ontologies rejected this view. Hierarchical ontologies assert that some entities exist on a more fundamental level and that other entities depend on them. Flat ontologies, on the other hand, deny such a privileged status to any entity.

 

Iconography, as a branch of art history, studies the identification, description and interpretation of the content of images: the subjects depicted, the particular compositions and details used to do so, and other elements that are distinct from artistic style. The word iconography comes from the Greek εἰκών ("image") and γράφειν ("to write" or to draw). [WRITING IMAGES]

In art history, "an iconography" may also mean a particular depiction of a subject in terms of the content of the image, such as the number of figures used, their placing and gestures. The term is also used in many academic fields other than art history, for example semiotics and media studies, and in general usage, for the content of images, the typical depiction in images of a subject, and related senses. Sometimes distinctions have been made between iconology and iconography, although the definitions, and so the distinction made, varies. When referring to movies, genres are immediately recognizable through their iconography, motifs that become associated with a specific genre through repetition.
