The phrase "a posteriori" means "based on experience or observation" in philosophy. It is pronounced /ə pɒsˈtɪəriəri/ in IPA phonetic transcription. The first syllable "a" is pronounced like the letter "uh" and the second syllable "posteriori" is pronounced with the stress on the "te-" and the "er-" sounds. The spelling of this phrase is derived from Latin and is used in English to describe knowledge that is gained through empirical evidence rather than pure reasoning.
The term "a posteriori" is an expression used in philosophy and epistemology to refer to a type of knowledge that is gained through empirical evidence or experience. Derived from Latin, "a posteriori" literally means "from the latter" or "from what comes after." It is the opposite of "a priori," which denotes knowledge obtained through reasoning or deduction without the need for experience.
In contemporary philosophical usage, "a posteriori" refers to knowledge that is based on observations, experiments, or sensory perceptions. It suggests that this knowledge is only accessible after one has had direct contact with the world or has gathered data through observation or experimentation.
A posteriori propositions are considered contingent, meaning that their truth or falsehood relies on what we can observe or experience in the world. They are grounded in empirical evidence and are subject to revision as new evidence emerges.
This term is often used in discussions related to scientific knowledge and induction. In science, researchers often establish knowledge claims based on repeated observations and experiments, which are considered a posteriori. These knowledge claims are considered tentative and subject to falsification. Scientists rely on the accumulation of a posteriori evidence to build models and theories about the workings of the natural world.
