The Great Man Theory
I fully agree with Herbert Spencer. The great man theory assumes that the reason these "great man" were famous lies in the "fact" that they must, in comparison to others, have a particular trait or a combination of, which set them apart from their human peers. Perhaps, they became famous, not because they had some special skills, but because they an idea or concept that impacted many individuals. Thus, as a consequence, someone found it worthy to make note of it within the literature.
