Also: Doubt, Critical Thinking
Skepticism or doubt is an attitude that recognizes our own fallibility, our tendency to err and to see ourselves and situations around us through a self-serving bias. When we embrace a healthy level of doubt, we are acknowledging that every person is finite and limited and sees the world through a glass darkly.
Doubt is the guardian of truth and a servant of humility. It is what allows us to detect our errors and to grow. It requires that we hold a part of ourselves in reserve when we embrace our own opinions or the teachings of others, recognizing that each of us is imperfect. When others reprove or correct us, doubt allows us to thoughtfully weigh their perspectives rather than assuming they are wrong. It keeps a door open for growth.
