19世纪的新康德式德国哲学家威廉·温德尔班德（Wilhelm Windelband）引入了这些术语并定义了它们的区别。 Windelband用名词性描述了一种试图进行大规模归纳的知识产生方法。 这种方法在自然科学中很常见，并且被许多人认为是科学方法的真正范例和目标。 通过一种非常规方法，人们可以进行仔细而系统的观察和实验，以得出可以在研究领域以外更广泛地应用的结果。 我们可能会将它们视为来自社会科学研究的科学定律或普遍真理。 实际上，我们可以在早期的德国社会学家马克斯·韦伯（Max Weber）的著作中看到这种方法，他写了有关创建理想类型和概念以用作一般规则的过程。
The 19th-century neo-Kantian German philosopher Wilhelm Windelband introduced these terms and defined their differences. Windelband uses a nominal description of a method of knowledge generation that attempts large-scale induction. This method is common in natural sciences and is considered by many to be the true paradigm and goal of scientific methods. With an unconventional method, one can carry out careful and systematic observations and experiments to arrive at results that can be applied more widely outside the field of research. We may think of them as scientific laws or universal truths from social science research. In fact, we can see this approach in the work of early German sociologist Max Weber, who wrote about the process of creating ideal types and concepts to use as general rules.
