The word "theory" is used in at least two senses--to denote a body of widely accepted laws or principles, as in "Darwinian theory" or "quantum theory," and to suggest a speculative hypothesis, often relying on mathematical analysis, that has not been experimentally confirmed. It is often said that there is no place for the second kind of theory in biology and that biology is not theoretical but based on interpretation of data. Here, ideas from a previous essay are expanded upon to suggest, to the contrary, that the second kind of theory has always played a critical role and that biology, therefore, is a good deal more theoretical than physics.
“理论”一词至少有两种用法——表示被广泛接受的法律或原则体系,例如“达尔文理论”或“量子理论”,以及表示一种推测性假设,这种假设通常依赖于未经实验证实的数学分析。人们常说,第二种理论在生物学中没有立足之地,生物学不是理论性的,而是基于对数据的解释。在这里,将以前的一篇文章中的观点扩展一下,以表明相反的观点,即第二种理论一直起着关键作用,因此生物学比物理学更具有理论性。
