It seems to me that to say that faith is blind, is to equate it with superstition. From Dictionary.com, we have:
Superstition: noun;
1. a belief or notion, not based on reason or knowledge, in or of the ominous significance of a particular thing, circumstance, occurrence, proceeding, or the like.
2. a system or collection of such beliefs.
3. a custom or act based on such a belief.
4. irrational fear of what is unknown or mysterious, especially in connection with religion.
5. any blindly accepted belief or notion.
Faith is defined as:
noun
1. confidence or trust in a person or thing: faith in another's ability.
2. belief that is not based on proof: He had faith that the hypothesis would be substantiated by fact.
3. belief in anything, as a code of ethics, standards of merit, etc.: to be of the same faith with someone concerning honesty.
4. belief in God or in the doctrines or teachings of religion: the firm faith of the Pilgrims.
5. a system of religious belief: the Christian faith; the Jewish faith.
6. the obligation of loyalty or fidelity to a person, promise, engagement, etc.: Failure to appear would be breaking faith.
7. the observance of this obligation; fidelity to one's promise, oath, allegiance, etc.
I thought it important to place these two definitions side by side so as to discuss the difference. To me, it becomes readily apparent that faith requires evidence whereas superstition does not. Superstition, as stated in items 1 & 5, is not based on reason... , but is based on blind acceptance. (The word 'knowledge' doesn't apply because faith is not based on knowledge but it is based on reason; (regardless of what Bill Maher says).
Whereas the definition of faith requires:
In item 1: Evidence that the person or thing in whom the confidence is placed can indeed be trusted. In this case, the persons in question are the prophets that have declared the reality of God over the millennia. I believe they can be trusted because they corroborate one another. This corroboration is the same that exists in peer review for scientists. Corroboration only requires the same results be stated. The method for arriving at those results may be a consideration for granting the quality of 'evidence', but that is not the definition of corroboration.
In item 2: Here is evidence that even atheists (in general) accept what scientists say on faith inasmuch as the scientist says that such hypotheses are justified based on 'some' evidence. No self respecting scientist would even form a hypothesis unless there were some evidence to suggest its probability even if that 'some' thing were his own reasoning.
In item 3. The evidence of history is appealed to here. Codes of ethics [morality] and standards of merit as these have had their impact on the rise and fall of nations validates their acceptance as evidence.
In item 4. See item 3; Since [most / some] religious beliefs have their tenets and doctrines based in natural law; that being a moral law, this is evidence that it comes under the heading of historical evidence. I do admit here that an interpretation of history in terms of the various doctrines of different religions becomes a factor. This is why I said 'most / some'.
Words have implicit meaning. Faith, by definition is not blind.
