“The practice which obtains amongst the Americans of fixing the standard of their judgment in themselves alone, leads them to other habits of mind. As they perceive that they succeed in resolving without assistance all the little difficulties which their practical life presents, they readily conclude that everything in the world may be explained, and that nothing in it transcends the limits of the understanding. Thus they fall to denying what they cannot comprehend; which leaves them but little faith for whatever is extraordinary, and an almost insurmountable distaste for whatever is supernatural.”

But there are things old and new which must not be contemplate by men´s eyes, because they know -or think they know- some things which other men have told them. Ah, it is the fault of our science that it wants to explain all; and if it explain not, then it says there is nothing to explain.”

“In the little world in which children have their existence, whosoever brings them up, there is nothing so finely perceived and so finely felt as injustice.”
