For, as a matter of fact, this very genuine privilege of old age is one which can be enjoyed only if a man is possessed of a certain amount of intellect; it will be appreciated most of all where there is real mental power; but in some degree by every one. It is only people of very barren and vulgar nature who will be just as sociable in their old age as they were in their youth. But then they become troublesome to a society to which they are no longer suited, and, at most, manage to be tolerated; whereas, they were formerly in great request. There is another aspect of this inverse proportion between age and sociability--the way in which it conduces to education. The younger that people are, the more in every respect they have to learn; and it is just in youth that Nature provides a system of mutual education, so that mere intercourse with others, at that time of life, carries instruction with it. Human society, from this point of view, resembles a huge academy of learning, on the Bell and Lancaster system, opposed to the system of education by means of books and schools, as something artificial and contrary to the institutions of Nature. It is therefore a very suitable arrangement that, in his young days, a man should be a very diligent student at the place of learning provided by Nature herself. But there is nothing in life which has not some drawback--_nihil est ab omni parte beatum_, as Horace says; or, in the words of an Indian proverb, _no lotus without a stalk_. Seclusion, which has so many advantages, has also its little annoyances and drawbacks, which are small, however, in comparison with those of society; hence anyone who is worth much in himself will get on better without other people than with them. But amongst the disadvantages of seclusion there is one which is not so easy to see as the rest. It is this: when people remain indoors all day, they become physically very sensitive to atmospheric changes, so that every little draught is enough to make them ill; so with our temper; a long course of seclusion makes it so sensitive that the most trivial incidents, words, or even looks, are sufficient to disturb or to vex and offend us--little things which are unnoticed by those who live in the turmoil of life.
