Lichfield, Augusts, 1775.

DEAR MADAM,—­Instead of forty reasons for my return, one is sufficient, —­that you wish for my company.  I purpose to write no more till you see me.  The ladies at Stowhill and Greenhill are unanimously of opinion, that it will be best to take a post chaise, and not to be troubled with the vexations of a common carriage.  I will venture to suppose the ladies at Streatham to be of the same mind.

You will now expect to be told, why you will not be so much wiser, as you expect, when you have lived twelve years longer.

It is said, and said truly, that experience is the best teacher; and it is supposed, that, as life is lengthened, experience is increased.  But a closer inspection of human life will discover, that time often passes without any incident which can much enlarge knowledge, or ratify judgment.  When we are young we learn much, because we are universally ignorant; we observe every thing, because every thing is new.  But, after some years, the occurrences of daily life are exhausted; one day passes like another, in the same scene of appearances, in the same course of transactions:  we have to do what we have often done, and what we do not try, because we do not wish to do much better; we are told what we already know, and, therefore, what repetition cannot make us know with greater certainty.

He that has early learned much, perhaps, seldom makes, with regard to life and manners, much addition to his knowledge; not only, because, as more is known, there is less to learn, but because a mind, stored with images and principles, turns inwards for its own entertainment, and is employed in settling those ideas, which run into confusion, and in recollecting those which are stealing away; practices by which wisdom may be kept, but not gained.  The merchant, who was at first busy in acquiring money, ceases to grow richer, from the time when he makes it his business only to count it.

Those who have families, or employments, are engaged in business of little difficulty, but of great importance, requiring rather assiduity of practice than subtilty of speculation, occupying the attention with images too bulky for refinement, and too obvious for research.  The right is already known:  what remains is only to follow it.  Daily business adds no more to wisdom, than daily lesson to the learning of the teacher.  But of how few lives does not stated duty claim the greater part!

Far the greater part of human minds never endeavour their own improvement.  Opinions, once received from instruction, or settled by whatever accident, are seldom recalled to examination; having been once supposed to be right, they are never discovered to be erroneous, for no application is made of any thing that time may present, either to shake or to confirm them.  From this acquiescence in preconceptions none are wholly free; between fear of uncertainty, and dislike of labour, every one rests while he might yet go forward; and they that were wise at thirty-three, are very little wiser at forty-five.
