“Concepts that have proven useful in ordering things easily achieve such authority over us that we forget their earthly origins and accept them as unalterable givens. Thus they come to be stamped as “necessities of thought”, “a priori givens”, etc. The path of scientific advance is often made impassable for a long time through such errors. For that reason, it is by no means an idle game if we become practiced in analyzing the long commonplace concepts and exhibiting those circumstances upon which their justification and usefulness depend, how they have grown up, individually, out of the givens of experience. By this means, their all-too-great authority will be broken. They will be removed if they cannot be properly legitimated, corrected if their correlation with given things be far too superfluous, replaced by others if a new system can be established that we prefer for whatever reason.”

“We can never dispense with language and the other symbol systems; for it is by means of them, and only by their means, that we have raised ourselves above the brutes, to the level of human beings. But we can easily become the victims as well as the beneficiaries of these systems. We must learn how to handle words effectively; but at the same time we must preserve and, if necessary, intensify our ability to look at the world directly and not through that half opaque medium of concepts, which distorts every given fact into the all too familiar likeness of some generic label or explanatory abstraction.”

“In just a little while we will forget all the things we used to want and adjust to the lives that we're given.”

“We must always keep in mind all legitimate authority is from God, and is given for protection, provision, and peace.”

“The light which we have gained, was given us, not to be ever staring on, but by it to discover onward things more remote from our knowledge. It is not the unfrocking of a priest, the unmitering of a bishop, and the removing hum from the Presbyterian shoulders that will make us a happy nation; no, if other things as great in the Church, and in the rule of life both economical and political, be not looked into and reformed, we have looked so long upon the blaze that Zwinglius and Calvin have beaconed up to us, that we are stark blind.”

“The wild things of this earth are not ours to do with as we please. They have been given to us in trust, and we must account for them to the generation which will come after us and audit our accounts.”
