The profound theories that Newton and Darwin arrived at were not initially easy for many people to understand, but as soon as this era came, it became easy for school students to understand these theories. And all of this is thanks to those writers who chose to simplify these theories and bring them closer to people's minds, and they pledged to make them the property of everyone. Hence, the great philosophical movements and lofty research were made easy for the common man thanks to that noble crowd of professors, lecturers, preachers, text commentators, and letter writers.
