“There is a thinking in primordial images, in symbols which are older than the historical man, which are inborn in him from the earliest times, eternally living, outlasting all generations, still make up the groundwork of the human psyche. It is only possible to live the fullest life when we are in harmony with these symbols; wisdom is a return to them.”

“We Sioux spend a lot of time thinking about everyday things which in our minds are mixed up with the spiritual. We see in the world around us many symbols that teach us the meaning of life. We have a saying that the white man sees so little, he must see with only one eye. We see a lot that you no longer notice. You could notice if you wanted to, but you are usually too busy. We Indians live in a world of symbols and images where the spiritual and commonplace are one...We try to understand them not with the head but with the heart.”

“However, the natural symbol, without our being sufficiently conscious of the fact, is identical with the reality of the world that appears to us, for every object in the natural world is at the same time a symbolic reality to us. The psyche certainly does not use an "object" of nature as a "symbol," but rather the experience of an "object" itself is always already symbolic experience. The star or tree in us is no less real and no less symbolic than it is in outward experience. For each possibility of experience either presupposes a spiritually forming, that is to say a symbolic activity, or is identical with this. That is, everything spiritual appears to us first not just in nature but as nature; or we could formulate this just as well the other way around: everything natural, whether outward or inward, appears to us as an image, that is to say as formed spirit. We are surrounded by images, inwardly and outwardly, but at the same time formed and determined in all our experiences by the natural symbol as though by a unitary natural-spiritual reality, for our psychic system only grasps that which appears to us as the real world through the world of natural symbolism.”

“Nature is a temple in which living columns sometimes emit confused words. Man approaches it through forests of symbols, which observe him with familiar glances.”

“No one is without Christianity, if we agree on what we mean by that word. It is every individual's individual code of behavior by means of which he makes himself a better human being than his nature wants to be, if he followed his nature only. Whatever its symbol - cross or crescent or whatever - that symbol is man's reminder of his duty inside the human race.”

“We live on a minute island of known things. Our undiminished wonder at the mystery which surrounds us is what makes us human. In science fiction we can approach that mystery, not in small, everyday symbols, but in bigger ones of space and time.”
