naturism

No; it is your naturism that is "narrowness and sectarianism."

Here we are, for once, just as far from naturism as from animism.

For some, animism is the primitive religion, of which naturism is only a secondary and derived form.

Thus it is only in appearance that naturism escapes the objection which we recently raised against animism.

Thus the objection which we have made to naturism would seem to be applicable to all possible systems of explanation.
