“The highest knowledge man can possess is that which is true in his own experience. If his experience is limited, so is his knowledge and he behaves accordingly.”

Foreword
The Still Centre (1939)
Context: A poet can only write about what is true to his own experience, not about what he would like to be true to his experience.
Poetry does not state truth, it states the conditions within which something felt is true. Even while he is writing about the little portion of reality which is part of his experience, the poet may be conscious of a different reality outside. His problem is to relate the small truth to the sense of a wider, perhaps theoretically known, truth outside his experience.

Mythology and the Individual (1997)
Context: The image of the cosmos must change with the development of the mind and knowledge; otherwise, the mythic statement is lost, and man becomes dissociated from the very basis of his own religious experience. Doubt comes in, and so forth. You must remember: all of the great traditions, and little traditions, in their own time were scientifically correct. That is to say, they were correct in terms of the scientific image of that age. So there must be a scientifically validated image. Now you know what has happened: our scientific field has separated itself from the religious field, or vice-versa. … This divorce this is a fatal thing, and a very unfortunate thing, and a totally unnecessary thing.
