conform = to comply, fit in, or be similar to what is normal

But if the natives refuse to conform themselves to their laws they drive them out of those bounds which they mark out for themselves, and use force if they resist, for they account it a very just cause of war for a nation to hinder others from possessing a part of that soil of which they make no use, but which is suffered to lie idle and uncultivated, since every man has, by the law of nature, a right to such a waste portion of the earth as is necessary for his subsistence.†

If any man has a mind to travel only over the precinct of his own city, he may freely do it, with his father's permission and his wife's consent; but when he comes into any of the country houses, if he expects to be entertained by them, he must labour with them and conform to their rules; and if he does this, he may freely go over the whole precinct, being then as useful to the city to which he belongs as if he were still within it.†
