rate the beams of the Sun are called Extension rays, because they have an extension in space[1]. And what a ray is you may easily see, if you observe the sun's light entering through a narrow chink into a darkened room, for it extends straight on, and is as it were brought up against[2] any solid body it encounters that cuts off the air beyond. There the ray comes to a standstill, neither slipping off nor sinking down. Such then should be the diffusion and circumfusion of the mind, never a diffusing away but extension, and it should never make a violent or uncontrollable impact against any obstacle it meets with, no, nor collapse, but stand firm and illuminate what receives it. For that which conducts it not on its way will deprive itself wilfully of its beams.
58. Dread of death is a dread of non-sensation or new sensation.[3] But either thou wilt feel no sensation, and so no sensation of any evil; or a different kind of sensation will be thine, and so the life of a different creature, but still a life.
59. Mankind have been created for the sake of one another.[4] Either instruct therefore or endure.[5]
60. One is the way of an arrow, another of the mind. Howbeit the mind, both when it cautiously examines its ground and when it is engaged in its enquiry, is none the less moving straight forward and towards its goal.
61. Enter into every man's ruling Reason, and give every one else an opportunity to enter into thine.[6]
