we are to take it, ex hypothesi, that Brown is
the soul of honour, and, like Mr. Facey Rumford, 'wouldn't tell a
lie if it was ever so'. The practical result is that, while Brown's
consciousness informs him, trumpet-tongued, that Green is at Rome,
'the residue of a forgotten impression' makes him (without his
knowing it) wag the table, which he does not intend to do, and
forces him to say through the tilts of the table, that Green is at
Machrihanish, while he believes that Green is at Rome.

The table-turners were laughed at, and many, if not all of them,
deserved ridicule. But see how even this trivial superstition
illuminates our knowledge of the human mind! A mere residuum of a
forgotten impression, a lost memory which Brown would have sworn, in
a court of justice, had never been in his mind at all, can work his
muscles, while he supposes that they are _not_ working, can make a
table move at which three other honourable men are sitting, and can
tell all of them what none of them knows. Clearly the expedient of
table-turning in court might be tried by conscientious witnesses,
who have forgotten the circumstances on which they are asked to give
evidence. As Dr. Carpenter remarks, quoting Mr. Lecky, 'our
doctrine of unconscious cerebration inculcates toleration for
differences not merely of belief, but of the moral standard'. And
why not toleration for 'immoral' actions? If Brown's residuum of an
impression can make Brown's muscles move a table to give responses
of which he is ignorant, why should not the residuum of a forgotten
impression that it would be a pleasant thing to shoot Mr. Gladstone
or Lord Salisbury, make Brown unconsciously commit that solecism?
It is a question of degree. At all events, if the unconscious self
can do as much as Dr. Carpenter believed, we cannot tell how many
other marvels it may perform; we cannot know till we investigate
further. If this be so, it is, perhaps, hardly wise or scientific
to taboo all investigation. If a mere trivial drawing-room
amusement, associated by some with an absurd 'animistic hypothesis,'
can, when explained by Dr. Carpenter, throw such unexpectedly
blinding light on human nature, who knows how much light may be
obtained from a research into more serious and widely diffused
superstitious practices? The research is, undeniably, beset with
the most thorny of difficulties. Yet whosoever agrees with Dr.
Carpenter must admit that, after one discovery so si
