stellar influences.

But Campanella is not very sure or clear about the future. Astrology

will come like a thief in the night. Therefore they expect a new
age, and perhaps also the end of the world.

The new age of knowledge was about to begin. Campanella, Bruno, and
Bacon stand, as it were, on the brink of the dividing stream,
tenduntque manus ripae ulterioris amore.

CHAPTER III

CARTESIANISM

If we are to draw any useful lines of demarcation in the continuous
flux of history we must neglect anticipations and announcements, and
we need not scruple to say that, in the realm of knowledge and
thought, modern history begins in the seventeenth century.
Ubiquitous rebellion against tradition, a new standard of clear and
precise thought which affects even literary expression, a flow of
mathematical and physical discoveries so rapid that ten years added
more to the sum of knowledge than all that had been added since the
days of Archimedes, the introduction of organised co-operation to
