Just as our mind is strengthened by contact with vigorous and well-ordered minds, so too it is impossible to overstate how much it loses and deteriorates by the continuous commerce and contact we have with mean and ailing ones. No infection is as contagious as that is. I know by experience what that costs by the ell. I love arguing and discussing, but with only a few men and for my own sake: for to serve as a spectacle to the great and indulge in a parade of your wits and your verbiage is, I consider, an unbecoming trade for an honourable gentleman.
