Quote by John Stuart Mill
"A being of higher faculties requires more to make him happy, is capable probably of more acute suffering, and is certainly accessible to it at more points, than one of an inferior type."
More from John Stuart Mill
"It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied."
"The only freedom which deserves the name is that of pursuing our own good in our own way."
"Actions are right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse of happiness."
"The person who can be only an easy optimist is a coward."
