In science and history, consilience is the principle that evidence from independent, unrelated sources can "converge" on strong conclusions. That is, when multiple sources of evidence are in agreement, the conclusion can be very strong even when none of the individual sources of evidence is significantly so on its own. Most established scientific knowledge is supported by a convergence of evidence: if not, the evidence is comparatively weak, and there will probably not be a strong scientific consensus.
A historian is a person who studies and writes about the past and is regarded as an authority on it. Historians are concerned with the continuous, methodical narrative and research of past events as relating to the human race; as well as the study of all history in time. Some historians are recognized by publications or training and experience. "Historian" became a professional occupation in the late nineteenth century as research universities were emerging in Germany and elsewhere.
Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion of past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole.
In law, a witness is someone who, either voluntarily or under compulsion, provides testimonial evidence, either oral or written, of what they know or claim to know.
Cognitive linguistics is an interdisciplinary branch of linguistics, combining knowledge and research from cognitive science, cognitive psychology, neuropsychology and linguistics. Models and theoretical accounts of cognitive linguistics are considered as psychologically real, and research in cognitive linguistics aims to help understand cognition in general and is seen as a road into the human mind.
In the study of history as an academic discipline, a primary source is an artifact, document, diary, manuscript, autobiography, recording, or any other source of information that was created at the time under study. It serves as an original source of information about the topic. Similar definitions can be used in library science and other areas of scholarship, although different fields have somewhat different definitions.
New Criticism was a formalist movement in literary theory that dominated American literary criticism in the middle decades of the 20th century. It emphasized close reading, particularly of poetry, to discover how a work of literature functioned as a self-contained, self-referential aesthetic object. The movement derived its name from John Crowe Ransom's 1941 book The New Criticism.
William Kurtz Wimsatt Jr. was an American professor of English, literary theorist, and critic. Wimsatt is often associated with the concept of the intentional fallacy, which he developed with Monroe Beardsley in order to discuss the importance of an author's intentions for the creation of a work of art.
Anecdotal evidence is evidence based only on personal observation, collected in a casual or non-systematic manner.
Credibility comprises the objective and subjective components of the believability of a source or message. Credibility dates back to Aristotle theory of Rhetoric. Aristotle defines rhetoric as the ability to see what is possibly persuasive in every situation. He divided the means of persuasion into three categories, namely Ethos, Pathos, and Logos, which he believed have the capacity to influence the receiver of a message. According to Aristotle, the term "Ethos" deals with the character of the speaker. The intent of the speaker is to appear credible. In fact, the speaker's ethos is a rhetorical strategy employed by an orator whose purpose is to "inspire trust in his audience." Credibility has two key components: trustworthiness and expertise, which both have objective and subjective components. Trustworthiness is based more on subjective factors, but can include objective measurements such as established reliability. Expertise can be similarly subjectively perceived, but also includes relatively objective characteristics of the source or message. Secondary components of credibility include source dynamism (charisma) and physical attractiveness.
"The Death of the Author" is a 1967 essay by the French literary critic and theorist Roland Barthes (1915–1980). Barthes's essay argues against traditional literary criticism's practice of relying on the intentions and biography of an author to definitively explain the "ultimate meaning" of a text. Instead, the essay emphasizes the primacy of each individual reader's interpretation of the work over any "definitive" meaning intended by the author, a process in which subtle or unnoticed characteristics may be drawn out for new insight. The essay's first English-language publication was in the American journal Aspen, no. 5–6 in 1967; the French debut was in the magazine Manteia, no. 5 (1968). The essay later appeared in an anthology of Barthes's essays, Image-Music-Text (1977), a book that also included his "From Work to Text".
Historical method is the collection of techniques and guidelines that historians use to research and write histories of the past. Secondary sources, primary sources and material evidence such as that derived from archaeology may all be drawn on, and the historian's skill lies in identifying these sources, evaluating their relative authority, and combining their testimony appropriately in order to construct an accurate and reliable picture of past events and environments.
Positivism is a philosophical school that holds that all genuine knowledge is either true by definition or positive—meaning a posteriori facts derived by reason and logic from sensory experience. Other ways of knowing, such as intuition, introspection, or religious faith, are rejected or considered meaningless.
Recorded history or written history describes the historical events that have been recorded in a written form or other documented communication which are subsequently evaluated by historians using the historical method. For broader world history, recorded history begins with the accounts of the ancient world around the 4th millennium BC, and it coincides with the invention of writing.
History is the systematic study and documentation of the human past.
In scholarship, a secondary source is a document or recording that relates or discusses information originally presented elsewhere. A secondary source contrasts with a primary source, which is an original source of the information being discussed; a primary source can be a person with direct knowledge of a situation or a document created by such a person.
Auxiliarysciences of history are scholarly disciplines which help evaluate and use historical sources and are seen as auxiliary for historical research. Many of these areas of study, classification and analysis were originally developed between the 16th and 19th centuries by antiquaries, and would then have been regarded as falling under the broad heading of antiquarianism. "History" was at that time regarded as a largely literary skill. However, with the spread of the principles of empirical source-based history championed by the Göttingen School of History in the late 18th century and later by Leopold von Ranke from the mid-19th century onwards, they have been increasingly regarded as falling within the skill-set of the trained historian.
The following outline is provided as an overview of and topical guide to social science:
The Göttingen school of history was a group of historians associated with a particular style of historiography located at the University of Göttingen in the late 18th century.
