Final answer:
Fideists believe that God exists through personal experiences and faith rather than through logical deductions or scientific experiments.
Step-by-step explanation:
According to Fideists, we know that God exists through C) Through personal experiences and faith. Fideism holds that the existence of God is not a truth that can be reached through logical deduction or scientific inquiry. Instead, God's existence is a matter of personal belief, stemming from individual experiences and the act of faith itself. This contrasts with empirical and rational arguments for God's existence, such as the cosmological or ontological arguments, which attempt to infer God's existence through a series of logical deductions or through the nature of existence itself. Fideists would argue that no amount of empirical evidence or logical reasoning can ultimately confirm the existence of God, as the divine transcends such human tools for understanding. Therefore, for a Fideist, faith and personal experiences are the primary means of acknowledging the presence of the divine.
