which had laid the earlier foundations. One school of vigorous action,
and still more vigorous talk, advises our generation to be done with the
past and make a fresh start on more ideal lines. This is not the voice
of science, which, just in proportion to its growth, has shown more and
more care for its origins and its past: and this is true at every stage
in the history of thought. The Greeks, fighting for freedom and
establishing in the city-state a new form of political organization for
the world, were yet in their scientific evolution true and grateful
successors of the priests who first compiled the observations necessary
for the scientific study of the heavens and founded the art of medicine.
The men of the Renascence, who were burnt and imprisoned for doubting
the verbal inspiration of Aristotle and the Bible, were in fact going
back to an earlier impulse than that of the scholastic philosophy. The
mathematics of Pappus and the mechanics of Archimedes had to be carried
further before the new sciences of which Aristotle had given the first
sketch could be securely founded. The pioneers of the sixteenth and
seventeenth centuries built therefore on the past, although accused of
impiety and revolution; and it must be so with any intellectual
construction which is to hold its own and form the future. So far from
there being any opposition in nature between history and science, the
two are but different aspects of one continuous enlargement of the human
spirit, which sees and lives more fully at each great moment of its
progress, and, so far as it is alive, is always informed by the real
achievements of the past. We illustrate this advance in the marvellous
record of our fifth chapter, and its spirit is summed up in the great
saying of Benedetto Croce that 'all history is contemporary history'.

But the reader may here begin not unnaturally to feel some impatience
with the argument, and to think that he is being carried into a region
of ideal imaginings quite out of touch with the realities of blood and
