1. In the author's opinion, ______.
A
[解析] 细节题。由第一段中“...all this is pure or theoretical knowledge, sought only for the purpose of understanding...”可推出选项A是正确的;人类追求纯知识,而并不了解其应用,故选项B错误;第一段中“Apart from these sciences is philosophy about which we will talk shortly.”是指“此外还有哲学,这将在后面讨论”,可见科学中包括哲学,故选项C错误;根据第二段中“...revolutionary scope is in large part unforeseen, except by the imagination of the Utopians”可知,纯科学革命性的结果可以被空想社会主义者预见,即选项D错误。故正确答案为A。
