記因（memes）

克里斯．安德森（Chris Anderson）在Free: The Future of a Radical Price一書說：

構想是終極的富足商品，傳播時邊際成本為零。構想一旦創造出來，想要散播得既廣且遠，豐富它們接觸的每一件東西。（在社會中，這種散播中的構想稱作「記因」〔memes〕。）（Ideas are the ultimate abundance commodity, which propagates at zero marginal cost. Once created, ideas want to spread far and wide, enriching everything they touch. (In society, such spread-ing ideas are called “memes.”)）
