These are constantly dissolved and reformed, until sometimes they form a crust round the central nucleus.
As the expansive force of the star diminishes in the course of time, it is encroached upon by neighboring vortices.

If the part of the encroaching star be of a less velocity than the star which it has swept up, it will presently lose its hold, and the smaller star pass out of range, becoming a comet.

But if the velocity of the vortex into which the incrusted star settles be equivalent to that of the surrounded vortex, it will hold it as a captive, still revolving and "wrapt in its own firmament." Thus the several planets of our solar system have been captured and held by the sun-vortex, as have the moon and other satellites.
But although these new theories at first created great enthusiasm among all classes of philosophers and scientists, they soon came under the ban of the Church.

While no actual harm came to Descartes himself, his writings were condemned by the Catholic and Protestant churches alike.
The spirit of philosophical inquiry he had engendered, however, lived on, and is largely responsible for modern philosophy.
In many ways the life and works of Leibnitz remind us of Bacon rather than Descartes.

His life was spent in filling high political positions, and his philosophical and scientific writings were by-paths of his fertile mind.
