To use two languages familiarly and without contaminating one by the other, is very difficult; and to use more than two is hardly to be hoped. The prizes which some have received for their multiplicity of languages may be sufficient to excite industry, but can hardly generate confidence.
Samuel JohnsonAt length weariness succeeds to labor, and the mind lies at ease in the contemplation of her own attainments without any desire of new conquests or excursions. This is the age of recollection and narrative; the opinions are settled, and the avenues of apprehension shut against any new intelligence; the days that are to follow must pass in the inculcation of precepts already collected, and assertion of tenets already received; nothing is henceforward so odious as opposition, so insolent as doubt, or so dangerous as novelty.
Samuel Johnson
