A priori justification
A priori justification refers to knowledge or beliefs that are considered justified independently of experience or observation. In other words, it's knowledge that we can know to be true without having to rely on specific evidence from the world. For example, mathematical truths, like "2 + 2 = 4," are known through reasoning alone, rather than through sensory experience. A priori knowledge often involves logical deductions and is foundational in fields like mathematics and philosophy, where certain truths are accepted based on rational thought rather than empirical data.

A priori justification refers to knowledge or beliefs that are justified independent of experience. This means we can know things or understand concepts without needing to observe or experiment. For example, in mathematics, we can determine that "2 + 2 = 4" based on logical reasoning alone, not by counting objects. A priori knowledge is often considered certain and necessary, like truths in logic or ethics, where no empirical evidence is required to validate them. It contrasts with a posteriori knowledge, which is based on observation and experience.
