Thereby,  some  of  the  questions  that  have  their  consideration  below 
arise in this regard. For example, is the emergence of criminal law norms 
dictated by nature or by rationality? Alternatively, how do we know what 
are their origin and background? In this way, to comment on them requires 
an acceptance of the fact that both of the mentioned factors play a role 
in the  existence of  criminal law  norms. However,  the  main  point  here  is 
the natural reason, or ethical principle, by which criminal-legal inuence 
appears. What is called rationality rather affects the form, while expressing 
it mechanically as the technical legal language. At the same time, moral 
norms,  which  are  an  attribute  of  the  essence  of  law,  rather  than  an 
instrument,  ll  these  norms  with  meaning.  We  can  claim  also,  that  Polo 
(2008)  characterized  normativism  and  ethical  rationalism  as  a  way  to 
consider ethics reductively (Polo, 2008).
Here is what Polo (2008) himself thought about the notion of law in its 
correlation with moral norms: 
Law and cultural customs are norms derived from ethical norms. What we call 
ethical norms are the laws most distinctive of the human being, most exclusively 
his, because their fulllment is free. And since freedom is responsible for this, they 
are not mechanisms; rather, freedom can decide not to fulll them (2008: 34). 
At the same time, such transcendental as love gures out to be the main 
positive norm, when dealing with natural law, according to Polo (Polo, 2010; 
Pia Tarazona, 1999). In this regard, the concept of synderesis (classically is 
an innate habit of the intellect, that judge what is good to do, and evil to 
avoid)  is  crucial  for  natural  law.  It  can  be  described  as  the  fundamental 
element of the human act of knowledge of ethics by nature (Vanney, 2007). 
Polo (2008) preferred to formulate it simply this way: “Do good, act; act 
as much as you can and improve your actuation” (2008: 106). In addition, 
classical authors also used to pay attention to the synderesis. For example, 
Saint Thomas Aquinas used it in his works (Aquinas, 2020).
Following  the  more  legislative  side  of  the  issue,  we  can  state  that  for 
Polo (1984), laws are something formally ctional, meaning they are  not 
given  to  a  man  by  nature;  rather,  they  are  invented  by  man  as  a  tool  in 
order to make it easier to resolve conicts and disputes. In this sense, Polo 
used to treat the concept of law as nomos (Polo, 1984). By that was meant 
the Ancient Greek word (νόμος),  which described laws governing human 
behavior mainly for the just distribution and rewards in case of litigation 
(Encyclopaedia Britannica,  2017;  about  the polian  notion  of  the law  as  a 
strong ction, Polo, Quién es el hombre, 1991; cf. also Riofrio, 2020, pro 
manuscrito).  Moreover,  the  law  as  such  can  be  considered  as  a  strong 
ction, meaning that its action prolongs physical reality, or objectivity, but 
does  not  have  sole  power,  because,  roughly  speaking,  it  does  not  have  a 
body  (Polo,  1991)  gives  an  example  of  a  wall  that  does  not  exist  in  fact; 
instead, there is a “no trespassing” sign). Thus, for Polo (1991), the law is a 
cultural phenomenon and has an empowering effect on man.
