Quote by Margaret Atwood
It must have been then that I began to lose faith in reasonable argument as the sole measure of truth.
Summary
This quote suggests that the speaker's belief in using rational arguments as the primary way to determine truth started to fade away. They likely experienced a shift in perspective or a specific event that made them doubt that reason alone could lead to a complete understanding of truth. This could indicate a recognition of the limitations of logical thinking or a realization that emotional, intuitive, or subjective aspects play a crucial role in perceiving and comprehending truth.
