Toolkit Theory or Toolbox Theory? The latter seems quite better.
I must also include the Pedagogy of the Oppressed in the paper as: Children who shape their own ZPDs and Toolboxes are essentially: For the Oppressed by the Oppressed.
To S. V. Smolensky, July 30/August 12, 1897:
Now I want to thank you and your sisters for the money that you gave me for the trip. When I left you for Glazunov's it suddenly occurred to me that now I would have to ask him to lend me some money. The thought of this horrified me. I couldn't have asked him, even if I didn't have your money in my pocket. My tongue would have been tied....
To N .S. Morozov, Moscow, October 22/November 4, 1901:
You're right, Nikita S.! Now I played the first part of my concerto, and just now it became clear that the transition from the first theme to the second will not fit, that in such a way the first theme doesn’t have a first theme, but an entry, and that not one idiot would believe, when I begin to play the second theme, that this is exactly the second theme. Everyone will think that this is the beginning of the concerto. In my opinion, I’m just desperate! And why did you come to me with your analysis five days prior to the performance of this concerto?
To A. B. Goldenweiser, Moscow, January 31/February 12, 1900:
Tomorrow, February 1, at nine o'clock in the evening, Princess Alexandra Lieven will drag me to Leo Tolstoy. I balk, because I'm afraid. However, Lieven told him about our visit and I can’t not go. Be a friend, come too, your presence encourages me. It will be all the easier.
