The term "a priori" is a Latin phrase that is used in English, and it means "from what comes before." It is used to describe knowledge or reasoning that is based on theory or deduction rather than on direct observation or experience.
Simple Explanation:
Adjective: When we say something is "a priori," we mean that it is based on reasoning or ideas, not on things we have seen or tested.
Adverb: When we use "a priori" in this way, we indicate that a conclusion is reached logically, without needing to look at specific facts or evidence.
Usage Instructions:
Use "a priori" when discussing theories, arguments, or judgments that are made without empirical evidence (facts gained from observation).
It is often used in academic or philosophical contexts.
Example:
Adjective: "The scientist made an a priori assumption about the results before conducting the experiment."
Adverb: "We can conclude a priori that the sun will rise tomorrow, based on past observations."
Advanced Usage:
In philosophy, "a priori" knowledge is contrasted with "a posteriori" knowledge, which is based on experience or empirical evidence. For example, mathematical truths (like 2 + 2 = 4) are often considered a priori because they can be understood without needing physical examples.
Word Variants:
A priori reasoning: The process of reasoning that comes before direct observation.
A posteriori: The opposite of a priori, meaning knowledge that comes after experience.
