[Note] that the mind in old age, taken over by dementia, does not take on suffering in itself — something which might allow it to be considered corruptible and mortal. With the organ mutated, and incapable out of unfitness to receive energy from the mind, it [merely] seems that the suffering of the organ is also the suffering of the mind animating it. For when the eye goes bleary, or is rendered unfit from old age, the sense [of sight] remains no less active; but the sensory organ becomes either passive, or totally useless and idle. And the reason why the sensory organ and the sensory capacity are not corrupted together is that the sensory capacity does not have its existence in this body, but in the spirit. So too when old peoples' eyes are weakened by time, with their membranes becoming thicker, wrinkly in a way, and not as transparent, and moreover when the fluids inside are made drier by time, congealed, and unable to transport the sensations of perceptions through the optic nerve — that is when it happens that old people see less well.¹ Also in reference to the demented it is not the mind that is demented; the organ's change for the worse and unfitness is what suffers, and produces [dementia] in the demented — not only in old age, but even in youth, when the body is taken over by certain brain-inflaming or lethargic illnesses. Or: that intense damage to the mind is called derangement; moderate damage is called delirium; and subdued damage is called raving.²
But liros [is] someone impudent; from "looking a lot" (lian oran); it is spelled with an iota.³
