, especially to those
who are inclined to idealistic pantheism. There can be no progress or
development in God, and the cosmic process as we know it cannot have a
higher degree of reality than the categories of time and place under
which it appears. As for the millennium of perfected humanity on this
earth, which some Positivists and others dream of,--Christianity has
nothing to say against it, but science has a great deal.) See below,
p. 328.]

[Footnote 405: In the Life of Charles Darwin there is an interesting
letter, in which he laments the gradual decay of his taste for poetry,
as his mind became a mere "machine for grinding out general laws" from
a mass of observations. The decay of religious _feeling_ in many men
of high character may be accounted for in the same way. The really
great man is conscious of the sacrifice which he is making. "It is an
accursed evil to a man," Darwin wrote to Hooker, "to become so
absorbed in any subject as I am in mine." The common-place man is
_not_ conscious of it: he obtains his heart's desire, if he works hard
enough, and God sends leanness withal into his soul.]

[Footnote 406: The metaphysical problem about the reality of time in
relation to evolution is so closely bound up with speculative
Mysticism, that I have been obliged to state my own opinion upon it.
It is, of course, one of the vexed questions of philosophy at the
present time; and I could not afford the space, even if I had the
requisite knowledge and ability, to argue it. The best discussion of
it that I know is in M'Taggart's _Studies in Hegelian Dialectic_, pp.
159-202. Cf. note on p. 23.]

APPENDIX A

Definitions Of "Mysticism" And "Mystical Theology"

The following definitions are given only as specimens. The list might
be made much longer by quoting from other Roman Catholic theologians,
but their definitions for the most part agree closely enough with
those which I have transcribed from Corderius, John a Jesu Maria, and
Gerson.

1. _Corderius_. "Theologia mystica est sapientia experimentalis, Dei
affectiva, divinitus infusa, quae mentem ab omni inordinatione puram
per actus supernaturales fidei spei et caritatis cum Deo intime
coniungit.... Mystica theologia, si vim nominis attendas, designat
quandam sacram et arcanam de Deo divinisque rebus notitiam."

2. _John a Jesu Maria_. "[Theologia mystica] est caelestis quaedam Dei
notitia per unionem voluntatis Deo inhaerentis elici
