第22句见：Day22

《哲学的故事》的第23句：序言中的第2段第10句。

Some ungentle reader will check us here by informing us that philosophy is as useless as chess, as obscure as ignorance, and as stagnant as content. "There is nothing so absurd," said Cicero, "but that it may be found in the books of the philosophers." Doubtless some philosophers have had all sorts of wisdom except common sense; and many a philosophic flight has been due to the elevating power of thin air. Let us resolve, on this voyage of ours, to put in only at the ports of light, to keep out of the muddy streams of metaphysics and the "many-sounding seas" of theological dispute. But is philosophy stagnant? Science seems always to advance, while philosophy seems always to lose ground. Yet this is only because philosophy accepts the hard and hazardous task of dealing with problems not yet open to the methods of science--problems like good and evil, beauty and ugliness, order and freedom, life and death; so soon as a field of inquiry yields knowledge susceptible of exact formulation it is called science. Every science begins as philosophy and ends as art; it arises in hypothesis and flows into achievement. Philosophy is a hypothetical interpretation of the unknown (as in metaphysics), or of the inexactly known (as in ethics or political philosophy); it is the front trench in the siege of truth. Science is the captured territory; and behind it are those secure regions in which knowledge and art build our imperfect and marvelous world. Philosophy seems to stand still, perplexed; but only because she leaves the fruits of victory to her daughters the sciences, and herself passes on, divinely discontent, to the uncertain and unexplored.
浙江大学版本：科学作为被攻克的领土，后面有稳固的城池，是知识和艺术共建的不甚完美但精彩非凡的世界。

解析

这句继续讲科学。captured territory 对应Day20中的“so soon as a field of inquiry yields knowledge susceptible of exact formulation it is called science.” 科学是哲学中被征服的领域，在科学之后，知识与艺术构建我们这个不完美但很精彩的世界。

1、imperfect and marvelous：现实中的imperfect与心态感受上的marvelous：“不完美但奇妙”。用这个来形容世界与生活都无不恰当。

She as a mother is imperfect and marvelous.

科学是一个已被征服的领域；在它之后是那些安全区域，在这里，知识和艺术共同构建了我们这个不完美但神奇的世界。
