Abdul Baha is an intelligent, well informed man, of fair sagacity. He was educated at home after the custom of Persia. He says of himself, "I have studied Arabic profoundly and know the Arabic better than the Arabians themselves. I have studied the Persian and Turkish in my native land, besides other languages of the East. But when I visit the West I need an interpreter."[4] He said to Doctor Jessup, "Yes, I know your Beirut Press and your books." His references to ancient and modern philosophers, to historical events and to European writers, quoting from the same, show some familiarity with literature.[5] He repudiates the claims of some of his disciples that he has no literary culture, as that of Abul Fazl[6] or of M. A. Lucas who says:[7] "He has had no access to books, yet his knowledge is unbounded." On this point Professor Cheyne remarks:[8] "His public addresses prove that through this and that channel he has imbibed something of humanistic and even scientific culture. He must have had some one to guide him in the tracks of modern inquiry. I venture to hope that his expounding may not, in the future, extend to philosophic, philological, scientific, and exegetical details. Abdul Baha may fall into error on secular problems, among which it is obvious to include Biblical and Koranic exegesis." "I am bound to say that Baha Ullah has made mistakes and the almost equally venerated Abdul Baha has made many slips."[9] A word should be said about the number of Bahais. I have many data on this point, but can here give only a summary. Regarding their numbers, the Bahais have indulged in gross exaggeration. "Millions" is the usual figure used by American Bahais. Thus Phelps[10] speaks of "the millions of Bahais in Persia." MacNutt, in "Unity through Love," declares that "His followers number millions from all the religious systems of the world." Kheiralla[11] says: "Abdul Karim, 1896, assured me that the believers in Baha were fifty millions. I wrote to Syria to ask. Sayid Mohammed, secretary of Abbas Effendi, said that the number was fifty-five million souls." Kheiralla afterwards denounces it as a gross deceit. As to Persia, they place the proportion at one-third or one-half. Dreyfus writes,[12] "Probably half the population of Persia is Bahai." Some judicious non-Bahai writers allow them half a million or less in Persia on a basis of ten millions of population. American missionaries, as Jordan at Teheran, Frame at Resht and Shedd at Urumia, calculate that the number in Persia does not exceed 100,000 to 200,000. After careful inquiry I agree with this estimate.
