* Rationalist: A rationalist believes that knowledge is primarily gained through reason and logic, rather than sensory experience.
* Idealist: An idealist believes that reality is fundamentally mental or spiritual, rather than physical or material. Empiricism is often associated with materialism.
* Dogmatist: A dogmatist holds firmly to certain beliefs, often without sufficient evidence or open to revision, which contradicts the empiricist's emphasis on evidence and observation.
* Apriorist: An apriorist believes that some knowledge is innate or independent of experience, which goes against the empiricist view that all knowledge originates from experience.
It's important to note that these are not mutually exclusive categories. Some philosophers may fall under multiple categories, and there are nuances within each category.
In summary: While a single "opposite" of an empiricist is difficult to define, the above terms represent philosophical perspectives that contrast with the core tenets of empiricism.
