We shall see that their system has no motive power at all in it, or that its motive power is simply the theistic faith they rejected, now tied up in a sack and left to flounder instead of walking upright.

We shall see that their system is either nothing, or that it is a mutilated reproduction of the very thing it professes to be superseding.

Once set it upon its own professed foundations, and the entire quasi-religious structure, with its visionary hopes, its impossible enthusiasms--all its elaborate apparatus for enlarging the single life, and the generation that surrounds it, falls to earth instantly like a castle of cards.

We are left simply each of us with our own lives, and with the life about us, amplified indeed to a certain extent by sympathy, but to a certain extent only--an extent whose limits we are quite familiar with from experience, and which positivism, if it tends to move them at all, can only narrow, and can by no possibility extend.

We are left with this life, changed only in one way.
