Part 3: "The Soul, Inspiration, Prophecy, and the Supernatural"
Ch. 5: "Moses as a Prophet"
There are other, momentous differences between how Moses communed
with G-d and how other prophets did.
For the others could receive their messages at any time and without
warning -- which is to say, passively and only when G-d deemed it
important to summon them. While Moses could summon G-d on his own, if you
will, and ask things of Him spontaneously.
And whereas other prophets only received the messages G-d judged it
essential for them to have right there and then, Moses was privy to nearly
anything and everything. "All keys were placed in his hands", as the
expression goes; and he was thus able to achieve levels of understanding
far beyond human ken.
