faith

Maimonides wrote in the Book of Mitzvot:
The first commandment is the commandment that we are commanded to believe in the Deity, and it is: that we believe that there is a cause and a reason, which is the agent of all that exists.
And this is what the Almighty said: “I am the Lord your God” (Exodus 20:2 and Deuteronomy 5:6).

1. What is “faith”?

2. Does faith contradict logic, as quoted: “Where knowledge ends, faith begins.”

3. How can faith be commanded? In order to receive the command, one must first believe that there is a command, meaning that the command is a logical paradox.

4. Have you discussed these issues at length elsewhere, and can you direct me?

5. By the way, do you know the source of the article I mentioned, “Where knowledge ends, faith begins”?

Thank you very much!
