Wikipedia says: “Faith is confidence or trust in a person or entity. Depending on the religion, faith is belief in a single god or multiple gods or in the doctrines or teachings of the religion. Informal usage of faith can be quite broad, including trust or belief without proof, and “faith” is often used as a substitute for “hope”, “trust” or “belief”.
Some critics of faith have argued that faith is opposed to reason. In contrast, some advocates of faith argue that the proper domain of faith concerns questions which cannot be settled by evidence. This is exemplified byattitudes about the future, which (by definition) has not yet occurred. Logical reasoning may proceed from any set of assumptions, positive or negative. In this view, faith is simply a positive assumption.”
Wiktionary: Blind (adjective): “Unable to see, due to physiological or neurological factors.”
“The improver of natural knowledge absolutely refuses to acknowledgle authority, as such. For him, skepticism is the highest of all duties; blind faith the one unpardonable sin.” Thomas Huxley.
Blind faith is also a piece I made last year, cause I could not give up on faith.
