"A Protestant minister of Oakland, California, in a recent address on the public school system of the United States, expressed himself as follows: 'In one of the schools of San Francisco Herbert Spencer's "Data of Ethics" was introduced as a text book of morals--as palpable a violation of the law forbidding sectarian instruction as the introduction of the Catholic or Methodist catechism; for Hebert Spencer belongs to a very small and narrow sect which promulgates the creed of Agnosticism.' "If the reverend speaker had taken the ground that the 'Data of Ethics' was too abstruse to be placed in the hands of public school pupils we should have felt inclined to sustain his objection. But when he says that to introduce such a book is to give a sectarian character to the school in which it is used, we must enter a protest. Science is never sectarian; philosophy is never sectarian. Sectarian teaching begins when you ask a man or a child to assume what cannot be proved, for the sake of keeping within the dogmatic lines that fence round some particular creed. The followers of Mr. Spencer may be in a minority, but they are no more a sect than were the adherents of the Copernican system of astronomy, or than are the believers in the Darwinian theory of natural selection. Mr. Spencer makes no appeal to faith, but finds his premises in the common experience of mankind. A pupil who was being taught out of the 'Data of Ethics' would be quite at liberty to dispute either the premises or the arguments of the author; and he would not be silenced by the declaration that Mr. Spencer is infallible. But when catechisms are taught they are taught, not as containing matter for discussion, but as containing doctrines that must not be disputed, on pain of more or less disagreeable consequences. Similarly when the Bible is read in school it is read not as a fallible record of events, or a fallible guide in morals, but as something absolutely authoritative--the very voice of God. It is perfectly obvious then, where sectarianism in education begins; it begins just at the point where doctrines of any kind accepted on faith by a portion of the community and not discussible on grounds of reason, are made a part of public school instruction. Sectarianism comes in whenever the teacher is obliged to say, 'Hush' to the inquiring scholar who wants his reason satisfied before he will believe. There is no sectarianism, on the other hand, in making use of a book which lays no claim to any kind of privilege, and which, therefore, cannot force the belief of anyone. The followers of Mr. Spencer do not form a sect because they have no beliefs which they wish to exempt from criticism or discussion, and because they hold themselves at full liberty to pass beyond the bounds of Mr. Spencer's thought whenever they can see their way to doing so. Mr. Spencer's 'Data of Ethics' may not contain all the truth on the subject of morals, but the truth
