...from the time of Kepler to that of Newton, and from Newton to Hartley, not only all things in external nature, but the subtlest mysteries of life and organization, and even of the intellect and moral being, were conjured within the magic circle of mathematical formulae.
Greatness and goodness are not means, but ends! Hath he not always treasures, always friends, The good great man? Three treasures, love and light, And calm thoughts, regular as infants' breath; And three firm friends, more sure than day and night, Himself, his Maker, and the angel Death.
To all new truths, or renovation of old truths, it must be as in the ark between the destroyed and the about-to-be renovated world. The raven must be sent out before the dove, and ominous controversy must precede peace and the olive wreath.
And all who heard should see them there, And all should cry, Beware! Beware! His flashing eyes, his floating hair! Weave a circle round him thrice, And close your eyes with holy dread, For he on honey-dew hath fed, And drunk the milk of Paradise.

And Winter slumbering in the open air,
Wears on his smiling face a dream of spring.
It cannot but be injurious to the human mind never to be called into effort: the habit of receiving pleasure without any exertion of thought, by the mere excitement of curiosity, and sensibility, may be justly ranked among the worst effects of habitual novel-reading.
