Theory:
His philosophy has proved to be useful to political conservatives, not only in the application of social class structure, but also in the concept of social justice that emphasizes individual responsibility for nature and behavior. Spencer supported the "law of equality and freedom", which is the basic principle of libertarianism. Under the condition of not infringing on the rights of others, each individual can do things according to his own choice. Many judges of the U.S. High Court draw conclusions based on this principle when facing the restrictions of government labor practice. But it's not just conservatives who use Spencer's theory to promote their views. Many sociologists use his theory to explain class war. Anarchists apply it to the belief of individual autonomy.
Writing:
Spencer also had a great influence on literature and rhetoric. His style philosophy (1852) initiated the formalism trend in writing. He pays close attention to the proper arrangement of English sentences and formulates guidelines for effective writing. Spencer's goal is to release prose from "resistance and inertia" Readers will not slow down because of their efforts to learn the above reasoning and the precise meaning of sentences. Only in this way can writers achieve the highest communication efficiency. This has become the most authoritative support for formalism in rhetoric.
