Via Caterina:

Tea is in my opinion a phantasticum, coffee an energeticum -- tea therefore possesses a disproportionately higher artistic rank. I notice that coffee disrupts the delicate lattice of light and shadows, the fruitful doubts that emerge during the writing of a sentence. One exceeds his inhibitions. With tea, on the other hand, the thoughts climb genuinely upward.
-- Ernst Jünger

Tea, by the way, is my preferred beverage. Coffee, bleh! Mwahaha.
