Expulsion from Paradise is in its main aspect eternal: that is to say, although expulsion from Paradise is final, and life in theworld unavoidable, the eternity of the process (or, expressed in temporal terms, the eternal repetition of the process) nevertheless makes it possible not only that we might remain in Paradise permanently, but that we may in fact be there permanently, no matter whether we know it here or not.
What Heaven has conferred is called The Nature; an accordance with this nature is called The Path of duty; the regulation of this path is called Instruction. The path may not be left for an instant. If it could be left, it would not be the path.
We may divide thinkers into those who think for themselves and those who think through others. The latter are the rule and the former the exception. The first are original thinkers in a double sense, and egotists in the noblest meaning of the word.
