In the second volume of *An Essay Concerning Human Understanding*, John Locke investigates the mechanics of language and the architecture of human knowledge. He begins by establishing that words are merely sensible signs of internal ideas, serving as arbitrary marks to communicate thoughts between individuals. Locke distinguishes between simple ideas, which are derived directly from sensation, and complex ideas, which are constructed by the mind. A central focus of his inquiry is the distinction between 'mixed modes' and 'substances.' Mixed modes, such as laws, crimes, and moral concepts, are entirely arbitrary creations of the understanding. Their essences are not found in nature but are voluntarily assembled by the mind to facilitate communication and social order. For instance, the specific definition of adultery or murder is a human invention, not a natural pattern, allowing societies to define crimes and punishments as they see fit. In contrast, the essences of substances—natural entities like gold or horses—are imperfect copies of nature. Human knowledge of substances is limited to nominal essences, which consist only of observable qualities like shape, color, and weight, rather than the true, hidden real essences of things. Locke argues that our categorization of substances often obscures truth because we settle for a few obvious traits while ignoring the infinite complexity of nature. The text culminates in a profound inquiry into knowledge itself. Locke defines the degrees of knowledge, distinguishing between certainty and probability, and explores the distinct roles of reason and faith. He concludes that while human knowledge is inherently limited and prone to error due to linguistic imperfections and the arbitrary nature of our ideas, the disciplined use of reason allows for significant progress. By understanding the artificial nature of language and the limits of our ideas, we can better navigate the world and understand our place within it, avoiding the confusion that arises from mistaking our nominal definitions for the true reality of things.
