it, as though doubt were really a destroyer. Of course, it
seems commonplace the moment you think of it; and, still for your peace
and for the restfulness of your mind as you look on the things that are
taking place about us, hold fast to this simple idea.

There is one other point which I wish to raise. What is the use of
criticism? What is the use of all this investigating? Why indulge in
all this doubt? And now let me give you an illustration which will lead
me to answering this question and enforcing the point I have in mind. A
farmer, if he selects a favorable piece of ground, plants good seed,
cultivates it properly, if the rain falls and the sun shines, and the
weather is propitious, will have a successful crop. Does it make any
difference now whether the farmer has correct ideas about soil and seed
and cultivation? Does it make any difference whether he has any true
conception of the nature and work of the sunshine in producing this
crop? In one sense, No. In another, a very important sense, Yes.
Suppose the farmer, having gotten into his mind the idea that the sun
is the source of all the life and growth of the things that he plants
and the crops he cultivates, should say, "Well, now, it does not make
any difference whether I have correct scientific theories about the sun
or not: the sun carries on his work just the same." I have heard people
say, over and over again, using an illustration like this: "What
difference does it make what your theories are about the spiritual
life, about the origin and nature of religion, about morality? If you
live a good life, the results are just the same, whatever your thinking
may be." And I grant it. But now suppose the farmer should say to
himself: "The sun is the source of all the life that I am able to
produce, that I see growing around me; and now I will worship him as a
god. I will pray to him, I will sing songs of praise to him, I will
bring birds and animals and burn sacrifices to him; and so I will win
his favor, and get him to produce these wonderful results for me."
Suppose he should so seek his results, and pay no attention to the
character of the soil, to the kind of seed he planted, or to proper
cultivation: would that make no difference?

Do you not see that theory may be of immense practical importance in
certain contingencies? Whether he has any knowledge of the sun or not,
if he complies with the laws, the conditions, if he is fortunately
obedient, then his
