cording to_ the memorandum
or major premise, since the grounds of the major premise and of the
conclusion are in fact the same (Mill: _Logic_, B. II. c. 3). Inductive
proofs may be stated in Syllogisms, and inductive inferences are drawn
_according to_ the Law of Causation.

Sec. 7. To assume that resemblance is a ground of inference, and that
substance and attribute, or cause and effect, are phenomena constantly
related, implies belief in the Uniformity of Nature. The Uniformity of
Nature cannot be defined, and is therefore liable to be misunderstood.
In many ways Nature seems not to be uniform: there is great variety in
the sizes, shapes, colours and all other properties of things: bodies
falling in the open air--pebbles, slates, feathers--descend in different
lines and at different rates; the wind and weather are proverbially
uncertain; the course of trade or of politics, is full of surprises. Yet
common maxims, even when absurd, testify to a popular belief that the
relations of things are constant: the doctrine of St. Swithin and the
rhyme beginning 'Evening red and morning grey,' show that the weather is
held to be not wholly unpredictable; as to human affairs, it is
said that 'a green Yule makes a fat churchyard,' that 'trade follows the
flag,' and that 'history repeats itself'; and Superstition knows that
witches cannot enter a stable-door if a horse-shoe is nailed over it,
and that the devil cannot cross a threshold inscribed with a perfect
pentagram. But the surest proof of a belief in the uniformity of nature
is given by the conduct of men and animals; by that adherence to habit,
custom and tradition, to which in quiet times they chiefly owe their
safety, but which would daily disappoint and destroy them, if it were
not generally true that things may be found where they have been left
and that in similar circumstances there are similar events.

Now this general belief, seldom distinctly conceived, for the most part
quite unconscious (as a principle), merely implied in what men do, is
also the foundation of all the Sciences; which are entirely occupied in
seeking the Laws (that is, the Uniformities) of Nature. As the
uniformity of nature cannot be defined, it cannot be proved; the most
convincing evidence in its favour is the steady progress made by Science
whilst trusting in it. Nevertheless, what is important is not the
comprehensive but indeterminate notion of Uniformity so much as a number
of First Princip
