All these processes are regarded as a series of manifestations of a vital principle in higher and higher forms. Oken, again, who carries Schelling's ideas into the region of biological science, seeks to reconstruct the gradual evolution of the material world out of original matter, which is the first immediate appearance of God, or the absolute.
A " circular system " was advocated by the eminent botanist Fries, and the views of Macleay met with the partial approbation of the celebrated entomologist Kirby, while at least as much may be said of the imaginative Oken, whose mysticism far surpassed that of the Quinarians.
He also admitted among his characteristics a physiological consideration (apparently derived from Oken 1) dividing the class A y es into two sections Altrices and Praecoces, according as the young were fed by their parents or, from the first, fed themselves.
On the other hand Oken (Isis, 1842, pp. 39 1 -394), though giving a summary of Nitzsch's results and classification, was more sparing of his praise, and prefaced his remarks by asserting that he could not refrain from laughter when he looked at the plates in Nitzsch's work, since they reminded him of the plucked fowls hanging in a poulterer's shop, and goes on to say that, as the author always had the luck to engage in researches of which nobody thought, so had he the luck to print them where nobody sought them.
Wolff, Goethe and Oken share the credit of having initiated these views, in regard especially to the structure of flowering plants and the Vertebrate skull.

Schelling's adherent Oken by his Lehrbuch der Naturphilosophie conveyed to his mind the life-long impression that God is the universe and Nature God's appearance.
This principle he endeavoured to deduce from his knowledge of geology, in contrast to Lorenz Oken, who developed the same theory on biological grounds.
