Quote by Ambrose Bierce
Who never doubted, never half believed. Where doubt is, there truth is - it is her shadow.
This quote suggests that doubt is an integral part of truth. Those who have never doubted anything and have complete belief in everything may not be truly aware of the essence of truth. Doubt acts as the shadow of truth, always present and associated with it. It implies that questioning and examining beliefs and ideas is vital in uncovering the authentic nature of truth. Without the presence of doubt, truth may be perceived as incomplete or even misleading. Thus, doubt serves as a catalyst for seeking and understanding truth.
