17. No clear-cut distinction can be drawn between professional and amateurs in science: exceptions can be found to any rule. Nevertheless, the word "amateur" does carry a connotation that person concerned is not fully integrated into the scientific community and, in particular, may not share its values.

科学领域的专业人员和业余爱好者之间划不出泾渭分明的界线：因为任何规则都有例外。然而，"业余"一词的确意味着相关人员不能充分融入职业科学界，尤其未能分享科学圈子的价值。

当然，人们现在对成功及其各种标志的兴趣似乎并不亚于先前。消夏别墅、欧陆旅行、宝马车地点、地名以及品牌或许会有变化，但这类事物在今天被人渴求的程度也似乎不会亚于一二十年前。

相反，我们被款待看到这样一些虚伪的壮观景象，他们似乎比以前的任何时候都更供应充足：美国式物质主义的批判者却拥有位于南安普顿的避暑山庄：激进书籍的出版商却在三星级餐厅享用一日三餐;倡导在人生各个阶段的参与民主制的，他的子女却就读于私立学校。
