Thoreau on Reforming Reformers:
The Reformer who comes recommending any institution or system to the adoption of men, must not rely solely on logic and argument, or on eloquence and oratory for his success, but see that he represents one pretty perfect institution in himself, the centre and circumference of all others, an erect man.
I ask of all Reformers, of all who are recommending Temperance—Justice—Charity—Peace, the Family, Community or Associative life, not to give us their theory and wisdom only, for these are no proof, but to carry around with them each a small specimen of his own manufactures, and to despair of ever recommending anything of which a small sample at least cannot be exhibited:—that the Temperance man let me know the savor of Temperance, if it be good, the Just man permit to enjoy the blessing of liberty while with him, the Community man allow me to taste the sweets of the Community life in his society.
I cannot bear to be told to wait for good results, I pine as much for good beginnings. We never come to the final results, and it is too late to start from perennial beginnings.
But alas, when we ask the schemer to show us the material of which his structure is to be built. He exhibits only fair looking words, resolute and solid words for the underpinning, convenient and homely words for the body of the edifice, poems and flights of the imagination for the dome and cupola.
