A quotation

No pure mystic ever loved mere mystery. The mystic does not bring doubts
or riddles: the doubts and riddles exist already. We all feel the riddle
of the earth without anyone to point it out. The mystery of life is the
plainest part of it. The clouds and curtains of darkness, the confounding
vapours, these are the daily weather of this world. Whatever else we have
grown accustomed to, we have grown accustomed to the unaccountable. Every
stone or flower is a hieroglyphic of which we have lost the key; with
every step of our lives we enter into the middle of some story which
we are certain to misunderstand. The mystic is not the man who makes
mysteries but the man who destroys them. The mystic is one who offers an
explanation which may be true or false, but which is always comprehensible
— by which I mean, not that it is always comprehended, but that it always
can be comprehended, because there is always something to comprehend. The
man whose meaning remains mysterious fails, I think, as a mystic.

—G. K. Chesterton, William Blake. London: Duckworth and Co. 131

My novice linguistics research: I wrote a paper for Linguistics 490 (senior seminar) taught by John Robertson, winter semester 1998 at Brigham Young University. It examines how Hebrew verb patterns (binyanim) may be semantically grouped using C.S. Peirce’s universal categories. The paper: Hebrew Verb Pattern Tendencies Clarified by Peirce’s Universal Categories (8.5″ x 11″). Reference chart: Roots in various binyanim chart (11″ x 17″).
