There's a whole field of Positive Psychology studying happiness (and pleasure) and yet the article doesn't mention it once.
The researchers have uncovered a tremendous amount about this topic (see Paul Bloom's "How Pleasure Works: The New Science of Why We Like What We Like", "Stumbling on Happiness" by Daniel Gilbert and the multi-author paper "If Money Doesn't Make You Happy Then You Probably Aren't Spending It Right"), and philosophers have thought about this topic for centuries.
The best reconciliation of philosophy and (recent studies in) psychology of it all is by Michael Bishop and his book: The Good Life: Unifying the Philosophy and Psychology of Well-Being
