Amid this corruption of morals who would expect to find the culture of philosophy? Notwithstanding, they have men whom they call philosophers, of whom one class lives in the woods and fields, and is extremely uncouth. These think it glorious to anticipate the hour of destiny, and arrange to have themselves burned alive when age has destroyed their activity, or the failure of health has made life burdensome. They regard death if waited for as a disgrace to their life, and when dissolution is simply the effect of old age funeral honours are denied to the dead body. They think that the fire is polluted unless the pyre receives the body before the breath has yet left it.[224] Those philosophers again who lead a civilised life in cities are said to observe the motions of the heavenly bodies, and to predict future events on scientific principles. These believe that no one accelerates the day of his death who can without fear await its coming.[225] They regard as gods whatever objects they value, especially trees, to violate which is a capital offence.[226] Their months they make to consist each of fifteen days, but they nevertheless assign to the year its full duration. They mark the divisions of time by the course of the moon, not like most nations when that planet shows a full face, but when she begins to appear horned, and hence, by fixing the duration of a month to correspond with this phase of the moon, they have their months one-half shorter than the months of other people.[227] Many other things have been related of them, but to interrupt with them the progress of the narrative I consider quite out of place. _Chapter X.—Campaign in the regions west of the Indus—Alexander captures Nysa, and visits Mount Merus—Siege of Mazaga, and its surrender_
