"...henceforward want nothing but a cup of good wine, a good bed, my back to the fire, my belly to the table, and a good deep dish..."
Rabelais, François. “Gargantua and Pantagruel, Illustrated, Book 1
I prefer to characterize the simplification of life as not a reduction but rather a distillation - more than a mere diminution but instead a refinement. The process is not so much a downgrading as a perfection (though the etymology of reduce - reducere - extends to "bring back, restore" which is more positive than depletion). Filtering at least captures the extraction of essential meaning or important aspects.
