Meditations 10.32

Let it not be in any man's power to say truly of thee that thou art not simple or that thou are not good; but let him be a liar whoever shall think anything of this kind about thee; and this is altogether in thy power. For who is he that shall hinder thee from being good and simple? Do thou only determine to live no longer, unless thou shalt be such. For neither does reason allow thee to live, if thou art not such.
