57. The sun seems to us diffused everywhere, pervasive of all things, yet never exhausted. This diffusion is a sort of extension, and hence the Greek word for rays is thought to be derived. You may observe the nature of a ray if you see it entering through some small hole into a darkened chamber. Its direction is straight; and it is reflected around when it falls upon any solid body, which shuts it off from the air beyond. There it stands and does not slip or fall. Now, such should be the flow and diffusion of the understanding; never exhausted, always extending; not violently or furiously dashing against the obstacles that meet it, nor falling aside, but resting there and illuminating whatever will receive it. That which will not transmit the light does but deprive itself of radiance. 58. He who dreads death dreads either the extinction of all sense or the experience of a new one. If all sense be extinguished, there can be no sense of evil. If a different sort of sense be acquired you become a different creature, and do not cease to live. 59. Men were created the one for the other. Teach them better then, or bear with them. 60. Mind moves in one way, and an arrow in another. The mind, when cautiously proceeding, or when casting round in deliberation about what to pursue, is nevertheless carried onward straight toward its proper mark. 61. Penetrate into the governing part of others; and also allow others to enter into your own. END OF THE EIGHTH BOOK. BOOK IX. 1. He who does injustice commits impiety. For since universal Nature has formed the rational animals for one another; each to be useful to the other according to his merit, and never hurtful; he who transgresses this her will is clearly guilty of impiety against the most ancient and venerable of the Gods. He who lies sins against the same divinity. For the nature of the whole is the nature of all things which exist; and things which exist are akin to all that has come to be. Nature, indeed, is called truth, and is the first cause of all truths. He, then, that lies willingly is guilty of impiety, in so far as by deceiving he works injury: and he also who lies unwillingly, in so far as he is out of tune with universal Nature, and in so far as he works disorder in the Universe by fighting against its design. He is at war with Nature who sets himself against the truth. He has neglected the means with which Nature furnished him, and cannot now distinguish false from true.
