First of all I want to remind you of the essential features of models. In my opinion they are: (i) drawing up a list of the variables to be considered; (ii) drawing up a list of the equations or relations the variables have to obey and (iii) testing the validity of the equations, which implies the estimation of their coefficients, if any. As a consequence of especially (iii) we may have to revise (i) and (ii) so as to arrive at a satisfactory degree of realism of the theory embodied in the model. Then, the model may be used for various purposes, that is, for the solution of various problems. The advantages of models are, on one hand, that they force us to present a "complete" theory by which I mean a theory taking into account all relevant phenomena and relations and, on the other hand, the confrontation with observation, that is, reality. Of course these remarks are far from new.

NOTES: Jean Cololère, a drummer in the colonial troops at Québec, was imprisoned for duelling in 1751. In the cell next to his was Françoise Laurent, who had been sentenced to hang for stealing. Except for letters of pardon, the only way at the time for someone under sentence of death to escape hanging was, for a man, to become a hangman, or, for a woman, to marry one. Françoise persuaded Cololère to apply for the vacant (and undesirable) post of executioner, and also to marry her.

Seek, therefore, thyself! But in finding oneself, does not one find one's own nothingness?... Carlyle answers (Past and Present, book iii, chap. xi.). "The latest Gospel in the world is, Know thy work and do it. Know thyself: long enough has that poor self of thine tormented thee; thou wilt never get to know it, I believe! Think it thy business, this of knowing thyself; thou art an unknowable individual: know what thou canst work at; and work at it, like Hercules. That will be thine better plan." ...and what is my work? - without thinking about myself, is to love God.... And on the other hand, in loving God in myself, am I not loving myself more than God, am I not loving myself in God?
Miguel de Unamuno
