Practical Reason Quotes

“There are progressions in which the last step is sui generis - incommensurable with the others - and in which to go the whole way is to undo all the labour of your previous journey. To reduce the Tao to a mere natural product is a step of that kind. Up to that point, the kind of explanation which explains things away may give us something, though at a heavy cost. But you cannot go on ‘explaining away’ for ever: you will find that you have explained explanation itself away. You cannot go on ‘seeing through’ things for ever. The whole point of seeing through something is to see something through it. It is good that the window should be transparent, because the street or garden beyond it is opaque. How if you saw through the garden too? It is no use trying to ‘see through’ first principles. If you see through everything, then everything is transparent. But a wholly transparent world is an invisible world. To ‘see through’ all things is the same as not to see.”
― C.S. Lewis, The Abolition of Man

“In similar fashion, Bellarmine's decree of 1616, banning the teaching of Copernicanism, looks like a calculated political move, designed to secure the interests of the church. Part of the traditional idea of an opposition between the "rational scientist" and the "prejudiced opponents of science" is best captured by noting that some people do not give the highest priority to impersonal cognitive goals but to certain practical ends (sometimes personal, sometimes impersonal) and that their actions are well designed for achieving these ends.”
― Philip Kitcher, The Advancement of Science: Science without Legend, Objectivity without Illusions
