The Eleate proceeds to comment upon the doctrines held by these opposing schools of thinkers respecting Essence or Reality. It is easier (he says) to deal with the last-mentioned, for they are more gentle. With the Materialists it is difficult, and all but impossible, to deal at all. Indeed, before we can deal with them, we must assume them to be for this occasion better than they show themselves in reality, and ready to answer in a more becoming manner than they actually do.[46] These Materialists will admit (Plato continues) that man exists--an animated body, or a compound of mind and body: they will farther allow that the mind of one man differs from that of another:--one is just, prudent, &c., another is unjust and imprudent. One man is just, through the habit and presence of justice: another is unjust, through the habit and presence of injustice. But justice must surely be _something_--injustice also must be _something_--if each may be present to, or absent from, any thing; and if their presence or absence makes so sensible a difference.[47] And justice or injustice, prudence or imprudence, as well as the mind in which the one or the other inheres, are neither visible or tangible, nor have they any body: they are all invisible.
