THREE: Above all, he exclaims, we must not fail to notice what effect this doctrine has on the minds of those whom they have persuaded to despise the world and all that it contains. Of the two chief methods for attaining the supreme good, one has sensual pleasure for its end, the other virtue, the effort after which begins and ends with God. Epicurus, by his denial of providence, leaves us no choice but to pursue the former. But this doctrine [Gnosticism], involving as it does a still more insolent denial of divine order and human law, laughs to scorn what has always been the accepted ideal of conduct, and, in its rage against beauty, abolishes temperance and justicethe justice that is associated with natural feeling and perpetuated by discipline and reasonalong with every other ennobling virtue. So, in the absence of true morality, they are given over to pleasure and utility and selfish isolation from other menunless, indeed, their nature is better than their principles. They have an ideal that nothing here below can satisfy, and so they put off the effort for its attainment to a future life, whereas they should begin at once, and prove that they are of divine race by fulfilling the duties of their present state. For virtue is the condition of every higher aspiration, and only to those who disdain sensual enjoyment is it given to understand the divine. How far our opponents are from realising this is proved by their349 total neglect of ethical science. They neither know what virtue is, nor how many virtues there are, nor what ancient philosophy has to teach us on the subject, nor what are the methods of moral training, nor how the soul is to be tended and cleansed. They tell us to look to God; but merely saying this is useless unless they can tell us what the manner of the looking is to be. For it might be asked, what is to prevent us from looking to God, while at the same time freely indulging our sensual appetites and angry passions. Virtue perfected, enlightened, and rooted in the soul, will reveal God to us, but without it he will remain an empty name.521

THREE:An apprentice may get a clear idea of this venting process by inspecting tubular core barrels, such as are employed in moulding pipes or hollow columns, or by examining ordinary cores about a foundry. Provision of some kind to 'carry off the vent,' as it is termed by moulders, will be found in every case. The venting of moulds is even more important than venting cores, because core vents only carry off gas generated within the core itself, while the gas from its exterior surface, and from the whole mould, has to find means of escaping rapidly from the flasks when the hot metal enters.395
