John Stuart Mill
English author, philosopher, economist
“No great improvements in the lot of mankind are possible until a great change takes place in the fundamental constitution of their modes of thought.”
“One person with a belief is equal to a force of ninety-nine with only interests.”
"The reasons for legal intervention in favor of children apply not less strongly to the case of those unfortunate slaves--the animals."
“It often happens that the universal belief of one age, a belief from which no one was free or could be free without an extraordinary effort of genius or courage, becomes to a subsequent age, so palpable an absurdity, that the only difficulty is to imagine how such an idea could ever have appeared credible.”
