There are some things which it is madness not to try to know but which it
is almost as much madness to try to know. Sometimes publishers, hoping
to buy the Holy Ghost with a price, fee a man to read for them and advise
them. This is but as the vain tossing of insomnia. God will not have
any human being know what will sell, nor when any one is going to die,
nor anything about the ultimate, or even the deeper, springs of growth
and action, nor yet such a little thing as whether it is going to rain
to-morrow. I do not say that the impossibility of being certain about
these and similar matters was designed, but it is as complete as though
it had been not only designed but designed exceedingly well.
