V. Whatsoever it be that happens unto thee, it is that which from all time was appointed unto thee. For by the same coherence of causes, by which thy substance from all eternity was appointed to be, was also whatsoever should happen unto it, destinated and appointed. VI. Either with Epicurus, we must fondly imagine the atoms to be the cause of all things, or we must needs grant a nature. Let this then be thy first ground, that thou art part of that universe, which is governed by nature. Then secondly, that to those parts that are of the same kind and nature as thou art, thou hast relation of kindred. For of these, if I shall always be mindful, first as I am a part, I shall never be displeased with anything, that falls to my particular share of the common chances of the world. For nothing that is behoveful unto the whole, can be truly hurtful to that which is part of it. For this being the common privilege of all natures, that they contain nothing in themselves that is hurtful unto them; it cannot be that the nature of the universe (whose privilege beyond other particular natures, is, that she cannot against her will by any higher external cause be constrained,) should beget anything and cherish it in her bosom that should tend to her own hurt and prejudice. As then I bear in mind that I am a part of such an universe, I shall not be displeased with anything that happens. And as I have relation of kindred to those parts that are of the same kind and nature that I am, so I shall be careful to do nothing that is prejudicial to the community, but in all my deliberations shall they that are of my kind ever be; and the common good, that, which all my intentions and resolutions shall drive unto, as that which is contrary unto it, I shall by all means endeavour to prevent and avoid. These things once so fixed and concluded, as thou wouldst think him a happy citizen, whose constant study and practice were for the good and benefit of his fellow citizens, and the carriage of the city such towards him, that he were well pleased with it; so must it needs be with thee, that thou shalt live a happy life.
