John Stuart Mill was a British philosopher of the 19th century who was a leading advocate of unitarianism "utilitarianism". This is defined by Wikipedia as:
"an ethical theory holding that the right course of action is the one that maximises the overall "good" consequences of the action."Mill wrote several books and essays; one such essay is called "On Representative Government", in which he writes:
"One person with a belief is a social power equal to ninety-nine who have only interests."...which is also the quote generously paraphrased above in this snapshot of a Twitter account. This was the only tweet on the account. Despite the fact that the account is likely to not be updated for a while, over 3000 people are "following" this account.
