To be agnostic means to hold the position that the truth about certain things, especially the existence of God or any ultimate reality, is unknown or unknowable. Agnostics neither firmly believe in the existence of a deity nor firmly deny it; instead, they claim that such knowledge is either currently unknown or inherently impossible to know. This stance emphasizes an open- minded, evidence-based approach, refraining from committing to beliefs without sufficient proof.
In broader terms, agnosticism can apply to any area of knowledge, proposing that some realities might be beyond human understanding. It is not about indecision but about recognizing the limitations of human reason and evidence in making certain knowledge claims, especially concerning metaphysical or religious questions.
Hence, being agnostic involves an ethical responsibility to withhold belief in certain claims until adequate evidence is available, maintaining a position of skepticism and inquiry rather than firm belief or disbelief.
