20.5 deber and tener que is possible |
Example |
(1) Has
somebody fainted, he has to be helped. |
The question is who says so?
There are two interpretations possible for (1) => the higher institution says so |
a) According
to the law everybody who faints has to be
helped, because otherwise it is a relevant
case for failing to render assistance in
an emergency and can be prosecuted. |
In case (2) the answer could be |
My uncle says that a person should be helped
if he faints |
1) no freedom of choice => the law says so
2) hardly any freedom of choice => moral obligation
3) there is freedom of choice => somebody demands
something
