Consequence Quotes - page 8
The first and most necessary topic in philosophy is that of the use of moral theorems, such as, "We ought not to lie;" the second is that of demonstrations, such as, "What is the origin of our obligation not to lie;" the third gives strength and articulation to the other two, such as, "What is the origin of this is a demonstration." For what is demonstration? What is consequence? What contradiction? What truth? What falsehood? The third topic, then, is necessary on the account of the second, and the second on the account of the first. But the most necessary, and that whereon we ought to rest, is the first. But we act just on the contrary. For we spend all our time on the third topic, and employ all our diligence about that, and entirely neglect the first. (51).

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.

The evil of marriage, as is it practiced in the European countries, extends further than we have yet described. The method is for a thoughtless and romantic youth of each sex, to come together, to see each other, for a few times, and under circumstances full of delusion and then to vow eternal attachment. What is the consequence of this? In almost every instance they find themselves deceived. They are reduced to make the best of an irretrievable mistake. They are led to conceive it their wiser policy, to shut their eyes upon realities, happy, if by any perversion of intellect, they can persuade themselves that they were right in their first crude opinion of each other. Thus the institution of marriage is made a system of fraud; and men who carefully mislead their judgement in the daily affair of their life, must be expected to have a crippled judgement in every other concern.
