TWO PSEUDO-SCIENCES--ALCHEMY AND ASTROLOGY In recent chapters we have seen science come forward with tremendous strides.

A new era is obviously at hand.

But we shall misconceive the spirit of the times if we fail to understand that in the midst of all this progress there was still room for mediaeval superstition and for the pursuit of fallacious ideals.

Two forms of pseudo-science were peculiarly prevalent--alchemy and astrology.

Neither of these can with full propriety be called a science, yet both were pursued by many of the greatest scientific workers of the period.
