A cultural life will exist outside of the Church whether it exists inside or not.  To be ignorant and simple now–not to be able to meet the enemies on their own ground–would be to throw down our weapons, and to betray our uneducated brethren who have, under God, no defence but us against the intellectual attacks of the heathen.  Good philosophy must exist, if for no other reason, because bad philosophy needs to be answered.”
