What would have been his later steps?
It would almost be worth while to complete the experiment.

It might be done if there were only a sufficient cause.

Men sneered at vivisection, and yet look at its results today! Why not advance science in its most difficult and vital aspect, the knowledge of the brain?
Had I even the secret of one such mind, did I hold the key to the fancy of even one lunatic, I might advance my own branch of science to a pitch compared with which Burdon-Sanderson's physiology or Ferrier's brain knowledge would be as nothing.

If only there were a sufficient cause! I must not think too much of this, or I may be tempted.

A good cause might turn the scale with me, for may not I too be of an exceptional brain, congenitally?
How well the man reasoned.
