Excerpt from The Open Court, Vol. 39: A Monthly Magazine Devoted to the Science of Religion, the Religion of Science, and the Extension of the Religious Parliament Idea; March, 1925 It has been maintained by Ogburn that man's bio-logical equip ment is practically a constant, both among the several races now and among those of the past for many thousands of years. Culture, how ever is an actively varying factor. When we say that man's biologi cal equipment is a constant, we admit that it varies between certain limits, both in the life of an individual, and over a long period of time, but we maintain that these limits are comparatively narrow, and that they remain practically equal, both from the point of view Of the several races now, and Of a perspective Of many thousand years.
