【中外历史人物评说】

材料：利奥十世教皇（1513-1521年在位）是文艺复兴时期最后一位教皇，他的父亲——洛伦佐·德·梅第奇是意大利政治家，外交家、艺术家，同时也是文艺复兴时期佛罗伦萨的实际统治者。利奥十世曾三次参加过教皇选举，三十八岁时被选为教皇。他是一位“生活的艺术家”，知道如何享受生活，却不知道如何去应付他所活着的年代。他以就职演说中的惊人之语“既然上帝授予我们教皇的职位，那么让我们享受它好了”而闻名，他代表了文艺复兴教皇的态度。利奥关注艺术美感和感官享受。开始他把路德的反叛当作“一个修士的争吵”，到他写了一封信谴责路德时，德意志北部的大部分地区已经站到那个真诚的圣奥古斯丁团教士一边了。

    据史料所述，拉斐尔对这位教皇一度怀有期望，因而对他表示异常的谦恭。1519年，拉斐尔在致利奥十世教皇的一封长信中曾这样说：“很多教皇有您老人家的这种称号，但是从来不象您那样具备如此伟大的学识、勇气和精神……有许多教皇只知肆意破坏，歪曲古代教堂、雕像、凯旋门等建筑……而您首先要考虑的应是关怀那些不多的建筑如何得以保全，它们是古代祖国和伟大的意大利的光荣。”

   Ask three people to look out the same window at a busy street corner and tell you what they see. Chances are you will receive three different answers. Each person sees the same scene（场景）, but each perceives（察觉）something different about it.
   Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket（罚单）. Another may say that he sees a rush-hour traffic jam at the intersection. The third may tell you that he sees a woman trying to cross the street with four children in tow（拉着）. For perception（感知） is the mind’s interpretation of what the senses—in this case our eyes—tell us.
   Many psychologists（心理学家） today are working to try to determine just how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene.
