摘要翻译：
五十多年来，分类学家在寻找一个独特的、全面的和有说服力的定义的同时，提出了许多不同的物种定义。这本专著表明，这些努力是不必要的，而且确实被证明是对一种意志的追求，因为他们没有认识到他们寻求完成的事情在理论上是不可能的。清楚而严格地理解物种定义背后的逻辑，既可以认识到影响物种定义的不可避免的模糊性，也可以对物种定义采取一种逻辑上令人信服的框架相关方法，也就是说，如果没有不一致，就不能被接受。一个附录反映了所得到的结论，将它们应用于一个智力上异想天开的分类学思想实验，推测一个新的人类物种出现的可能性。

英文摘要：
  For more than fifty years, taxonomists have proposed numerous alternative definitions of species while they searched for a unique, comprehensive, and persuasive definition. This monograph shows that these efforts have been unnecessary, and indeed have provably been a pursuit of a will o' the wisp because they have failed to recognize the theoretical impossibility of what they seek to accomplish. A clear and rigorous understanding of the logic underlying species definition leads both to a recognition of the inescapable ambiguity that affects the definition of species, and to a framework-relative approach to species definition that is logically compelling, i.e., cannot not be accepted without inconsistency. An appendix reflects upon the conclusions reached, applying them in an intellectually whimsical taxonomic thought experiment that conjectures the possibility of an emerging new human species.
