both brilliant
composers [Inclusion], the one musical, the other literary, the one a
representative of the music of the future, the other of the obsolete
polemic of the past [Exclusion], Richard Wagner and Louis Veuillot, were
born in the same year, 1813, and died in the same year, 1883. The last
point is a double Concurrence.
Two foremost harbingers of modern thought [Inclusion], Voltaire and
J. J. Rousseau, died in 1778--[Concurrence]. Both gained for themselves
the reputation of having been the most reckless antagonists of
Christianity [Inclusion]. And still the one dedicated a church to the
service of God, whilst the other in his "Emile" wrote a vindication of
Christianity [Exclusion as to each of them, Inclusion as to both of
them].
A little practice makes the pupil prompt in dealing with any figures
whatever. Take the height of Mount Everest, which is 29,002 feet. We
have all heard that it is more than five miles high. Let us test this
statement. There are 5,280 feet in a mile, multiply 5,280 by 5, and we
have 26,400. Hence we see that Mount Everest being 29,002 feet high must
be more than five miles high. Half of a mile is 5,280 feet divided by 2,
or 2,640 feet. Add this to 26,400 and we have 29,040. Hence we see that
Mount Everest is 51/2 miles high lacking 38 feet, or that if we add
38 feet to its height of 29,002, it would then be exactly 51/2 miles high.
Can we then forget that it is exactly 29,002 feet high?
Shakespeare was born in 1564 and died in 1616. The First Folio Edition
of his works was printed in 1623, the Second in 1632, the Third in 1664,
and the Fourth in 1685. Can we fix these events infallibly in our
memories? We can begin with whichever date we prefer. If we add
together the figures of the year of his birth, 1564, they make 16. All
the dates hereafter considered occurred in 1600, &c. We can thus
disregard the first 16 and consider only the last two figures which
constitute the fraction of a century.
Let us begin with his death in 1616 in the _sixteens_. Is not this a
vivid collocation of figures? Can we forget it as applied to the great
dramatist? Now if we double the last 16, it gives us the date of the
second Folio in [16]32 and 32 reversed gives us the date of the first
Folio. Again, seven years after his death ["seven ages of man"] his
first Folio was published in 1623. The second Folio was published in
1632 or 23 reversed, and the third Folio in 1664, or 32 doubled, and
just 100
