A member of the Democratic Party and regarded as a progressive, Warren has focused on consumer protection, equitable economic opportunity, and the social safety net while in the Senate. Warren was a candidate in the 2020 Democratic Party presidential primaries, ultimately finishing third.

Born and raised in Oklahoma, Warren is a graduate of the University of Houston and Rutgers Law School and has taught law at several universities, including the University of Houston, the University of Texas at Austin, the University of Pennsylvania, and Harvard University. She was one of the most influential professors in commercial and bankruptcy law before beginning her political career. Warren has written 12 books and more than 100 articles.

Warren's first foray into public policy began in 1995, when she worked to oppose what eventually became a 2005 act restricting bankruptcy access for individuals. During the late 2000s, her national profile grew after her forceful public stances in favor of more stringent banking regulations after the financial crisis of 2007–08. She served as chair of the Congressional Oversight Panel of the Troubled Asset Relief Program, and proposed and established the Consumer Financial Protection Bureau, for which she served as the first special advisor under President Barack Obama.

In 2012, Warren defeated incumbent Republican Scott Brown and became the first female U.S. senator from Massachusetts. She won re-election by a wide margin in 2018, defeating Republican nominee Geoff Diehl. On February 9, 2019, Warren announced her candidacy in the 2020 United States presidential election. She was briefly considered the front-runner for the Democratic nomination in late 2019, but support for her campaign dwindled. She withdrew from the race on March 5, 2020, after Super Tuesday.

user: What is Ontology?

assistant: <think>
"In metaphysics, ontology is the philosophical study of being, as well as related concepts such as existence, becoming, and reality.

Ontology addresses questions like 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 the 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."</think>
