Doxastic is an adjective drawn from the Greek doxa (δόξα), meaning belief or opinion.
In contemporary philosophy, particularly epistemology and philosophy of mind, the term is used to describe anything that pertains to beliefs, as opposed to knowledge, evidence, or truth itself.
A doxastic state is simply a state of believing something. If you believe that the sun will rise tomorrow, that belief, regardless of whether it is justified, true, or consciously articulated, is a doxastic state. By contrast, non-doxastic states include perceptions, emotions, sensations, or habits that may influence belief but are not themselves beliefs.
Philosophers often contrast doxastic with:
Epistemic (relating to knowledge or justification),
Alethic (relating to truth),
Pragmatic (relating to action or utility).
This distinction matters because a belief can be doxastically coherent while epistemically weak, or epistemically strong while psychologically unstable.
One of the most important uses of the term appears in debates about doxastic responsibility: to what extent are we morally or rationally responsible for what we believe? Since beliefs are not typically chosen in the same way actions are, philosophers ask whether it makes sense to praise or blame someone for holding a particular belief.
This question becomes especially sharp in discussions of misinformation, ideology, and self-deception. If beliefs are shaped by unconscious biases, social conditioning, or cognitive shortcuts, how much control do we really have over our doxastic lives?
Calling something “doxastic” forces precision. It reminds us that:
Believing is not the same as knowing.
Confidence is not evidence.
Coherence is not truth.
In an era saturated with information doxastic is a useful word because it slows the conversation down. It asks us to distinguish between what we believe, why we believe it, and whether that belief deserves to survive contact with reality.
In short: before arguing about facts, it is often worth examining the doxastic ground beneath them.
