and in later thinkers we see a movement through Neo-Platonism towards real Platonism which is approached by Mulla Hādī's Philosophy. But pure speculation and dreamy mysticism undergo a powerful check in Bābism which, unmindful of persecution, synthesises all the inherited philosophical and religious tendencies, and rouses the spirit to a consciousness of the stern reality of things. Though extremely cosmopolitan and hence quite unpatriotic in character, it has yet had a great influence over the Persian mind. The unmystic character and the practical tone of Bābism may have been a remote cause of the progress of recent political reform in Persia. ERRATA P. 4, Note 4, l. 1, read Buudahish for Buudadisḥ.
