Abstract: Observations can be done relying on some elements of theories not explicitly. Good knowledge has
part of it theories and part of it observations. We are taught to resort to calculations but calculations are only
part of mathematics and of statistics. There are in some parts of the reality some crossroads of disciplines that
the over-specialized people try to ignore.
Until the beginning of the sixties, there were some deepened thinking and after that people were afraid of
deepened thinking except for the creation of the internet. Until the beginning of the sixties, there were also
some big changes outside the Western World but most of them did not lead to successes despite the
multiplication of empirical studies and because of the lack of realistic theories. The end is much more
important than the means but any damages have to be considered a part of the end.
