Would it not be a luxury to stand up to one’s chin in some retired swamp for a whole summer’s day?

It is only when we forget all our learning that we begin to know. I do not get nearer by a hair’s breadth to any natural object so long as I presume that I have an introduction to it from some learned man. To conceive of it with a total apprehension I must for the thousandth time approach it as something totally strange. If you would make acquaintance with the ferns you must forget your botany. You must get rid of what is commonly called knowledge of them. Not a single scientific term or distinction is the least to the purpose, for you would fain perceive something, and you must approach the object totally unprejudiced. You must be aware that nothing is what you have taken it to be…You have got to be in a different state from common. Your greatest success will be simply to perceive things as they are.
