text: **Areas of research**
  
  Logic is studied in various fields. In many cases, this is done by applying its formal method to specific 
  topics outside its scope, like to ethics or computer science.[156] In other cases, logic itself is made the 
  subject of research in another discipline. This can happen in diverse ways. For instance, it can involve 
  investigating the philosophical assumptions linked to the basic concepts used by logicians. Other ways 
  include interpreting and analyzing logic through mathematical structures as well as studying and 
  comparing abstract properties of formal logical systems.[157]
