Final answer:
John Stuart Mill's defense of freedom of expression is driven by the promotion of truth and knowledge, prevention of the tyranny of the majority, encouragement of individual autonomy and self-development, and fostering a diverse and pluralistic society.
Step-by-step explanation:
One of the reasons for John Stuart Mill's defense of freedom of expression is to promote the search for truth and knowledge. Mill believed that by allowing individuals to freely express their ideas and opinions, society can benefit from a marketplace of ideas where the best ideas rise to the top through open debate and discussion.
Another reason is to prevent the tyranny of the majority. Mill argued that without freedom of expression, the majority could silence dissenting voices and oppress minority opinions.
Furthermore, Mill defended freedom of expression to encourage individual autonomy and self-development. He believed that individuals should have the freedom to pursue their own interests and develop their intellectual and moral capacities.
Lastly, Mill advocated for freedom of expression to foster a diverse and pluralistic society. He argued that by allowing different views and opinions to be expressed, society can benefit from the diversity of ideas and perspectives.
