Who is more humble? The scientist who looks at the universe with an open mind and accepts whatever the universe has to teach us, or somebody who says everything in this book must be considered the literal truth and never mind the fallibility of all the human beings involved? - Carl Sagan
To confess your fallibility and then do nothing about it is not humble; it is boasting of your modesty. - Eliezer Yudkowsky
Even the knowledge of my own fallibility cannot keep me from making mistakes. Only when I fall do I get up again. - Vincent Van Gogh
You could just as well say that an agnostic is a deeply religious person with at least a rudimentary knowledge of human fallibility. - Carl Sagan
Reason itself is fallible, and this fallibility must find a place in our logic. - Nicola Abbagnano
Our greatest challenge today...is to couple conviction with doubt. By conviction, I mean some pragmatically developed faith, trust, or centeredness; and by doubt I mean openness to the ongoing changeability, mystery, and fallibility of the conviction. - Kirk J. Schneider
