有人曾这样评价说：胡适是水，鲁迅是酒。酒虽好，有时却容易醉人；水虽淡，却又必不可少。纵观整部现代史，无论是文学变革还是北大复兴，胡适都是其中浓墨重彩的一笔。可以说，正是有了胡适这汪源远流长的水域的灌溉与滋润，北大方才成为今日的北大。本书作者一路寻访胡适曾走过的足迹，在时光的荒野里捡起了他留下的点点滴滴，重新塑造了一个有血有肉的胡适。(Someone has ever commented that: Hu Shi is water, while Lu Xun is wine. Wine tastes good, but sometimes it is easy to get intoxicated; water, although light, but it is absolutely necessary. Throughout the entire modern history, no matter in literature revolution or North revival, Hu Shi played an important role. It can be said that just because of Hu Shi's long time efforts and hard work, Peking University can be one of the top universities today. The author of this book have trailed the footsteps of Hu Shi, and picked up the little bit left by Hu Shi in the wilderness of time, and recreated a vivid and substantial Hu Shi.)
