Don't let anyone truthfully say that you are not simple, sincere, or good. Let them be wrong if they think badly of you. This is entirely up to you. Who could stop you from being simple or good? Just decide that you would rather not live than not be this kind of person. It doesn't make sense for someone to live if they are not like this.
Let it not be in any man's power, to say truly of thee, that thou art not truly simple, or sincere and open, or not good. Let him be deceived whosoever he be that shall have any such opinion of thee. For all this doth depend of thee. For who is it that should hinder thee from being either truly simple or good? Do thou only resolve rather not to live, than not to be such. For indeed neither doth it stand with reason that he should live that is not such.
