_In each of the Palætiological Sciences, we can ascend to remote periods by a chain of causes, but in none can we ascend to a_ beginning _of the chain._ (X. 3.) CXII. _Since the Palætiological sciences deal with the conceptions of historical cause,_ History, _including_ Tradition, _is an important source of materials for such sciences._ (X. 4.) CXIII. _The history and tradition which present to us the providential course of the world form a_ Sacred Narrative; _and in reconciling the Sacred Narrative with the results of science, arise inevitable difficulties which disturb the minds of those who reverence the Sacred Narrative._ (X. 4.) {26} CXIV. _The disturbance of reverent minds, arising from scientific views, ceases when such views become familiar, the Sacred Narrative being then interpreted anew in accordance with such views._ (X. 4.) CXV. _A new interpretation of the Sacred Narrative, made for the purpose of reconciling it with doctrines of science, should not be insisted on till such doctrines are clearly proved; and when they are so proved, should be frankly accepted, in the confidence that a reverence for the Sacred Narrative is consistent with a reverence for the Truth._ (X. 4.) CXVI. _In contemplating the series of causes and effects which constitutes the world, we necessarily assume a_ First Cause _of the whole series._ (X. 5.) CXVII. _The Palætiological Sciences point backwards with lines which are broken, but which all converge to the_ same _invisible point: and this point is the Origin of the Moral and Spiritual, as well as of the Natural World._ (X. 5.)
