“I shall present as certain only those data corroborated by exhaustive research, or by my own personal investigations, as I am not untraveled for a bookish man. Wherever doubt exists, I shall unambiguously state its degree and nature, along with whatever grounds I may have for preferring one hypothesis over another. If, despite all I have said, the reader disdains such honest ambiguity, and stubbornly prefers the unequivocal assertiveness to be found in factitious travelogues penned by raffish “explorers,” or in the specious “natural histories” compiled by crapulous and unprincipled hacks who have never left their squalid lofts in Scrivener’s Row, then there is nothing further I can do, and I leave him, with apologies, to his deception.”

The Anthem of Humanity
The Vision: Reflections on the Way of the Soul (1994)
Context: I have existed from all eternity and, behold, I am here; and I shall exist till the end of time, for my being has no end.
I soared into limitless space and took wing in the imaginal world, approaching the circle of exalted light; and here I am now, mired in matter.
I listened to the teachings of Confucius, imbibed the wisdom of Brahma, and sat beside Buddha beneath the tree of insight. And now I am here, wrestling with ignorance and unbelief. I was on Sinai when Yahweh shed his effulgence on Moses; at the River Jordan I witnessed the miracles of the Nazarene; and in Medina I heard the words of the Messenger to the Arabs. And here I am now, a captive of confusion.

As quoted in Truth Against the World : Frank Lloyd Wright speaks for an organic architecture (1987) edited by Patrick J. Meehan <!-- p. 29 -->
Context: God is the great mysterious motivator of what we call nature and it has been said often by philosophers, that nature is the will of God. And, I prefer to say that nature is the only body of God that we shall ever see. If we wish to know the truth concerning anything, we'll find it in the nature of that thing.
