I think it's undeniable that Alice Waters, for instance, has a very coherent "philosophy of food." It isn't the kind of thing that would be expressed in some academic treatise, but you'd be able to learn it by eating at Chez Panisse. Anyone who starts an entirely new genre of food has to be said to have her own "philosophy" of it. But the language it's expressed in isn't English or French or German--it's not linear and verbal, it's a gustatory "language." There are ingredients combined into dishes just as words are shaped into paragraphs. There are appetizers (introductions, forewords), entrees (chapters), and desserts (conclusions, afterwords). Some ideas are epigrammatic, pithy one-liners, like a one-or-two-bite amuse bouche. Some are whimsical and light-hearted, others are grimly serious. Some philosophers are direct and to the point, and some can drone on ALL EVENING. I do think food at the highest levels, like art or architecture at the highest levels, can use a kind of non-verbal language that expresses coherent ideas. I mean, what about "less is more"? What about "make it new"? What about "dare to be naive"?
