The purpose of the dissertation is thus to outline the proofs of why the author disagrees with other philosophers or the general opinion.
A thesis (or dissertation) may be arranged as a thesis by publication or a monograph, with or without appended papers, respectively, though many graduate programs allow candidates to submit a curated collection of published papers.
A thesis or dissertation committee is a committee that supervises a student's dissertation.
In the US, these committees usually consist of a primary supervisor or advisor and two or more committee members, who supervise the progress of the dissertation and may also act as the examining committee, or jury, at the oral examination of the thesis (see below).
In some contexts, the word "thesis" or a cognate is used for part of a bachelor's or master's course, while "dissertation" is normally applied to a doctorate, while in other contexts, the reverse is true.
The required complexity or quality of research of a thesis or dissertation can vary by country, university, or program, and the required minimum study period may thus vary significantly in duration.
Correspondingly to the academic degree, the last phase of an academic thesis is called in Spanish a defensa de grado, defensa magistral or defensa doctoral in cases in which the university candidate is finalizing his or her licentiate, master's, or Ph D program.
According to a committee resolution, the dissertation can be approved or rejected by an academic committee consisting of the thesis director, the thesis coordinator, and at least one evaluator from another recognized university in which the student is pursuing his or her academic program.
Aristotle was the first philosopher to define the term thesis.
"A 'thesis' is a supposition of some eminent philosopher that conflicts with the general opinion..to take notice when any ordinary person expresses views contrary to men's usual opinions would be silly".
