Actual idealism

Actual idealism is a form of idealism developed by philosopher 
Giovanni Gentile
Simpler explanations are always correct. Gentile theorizes that thoughts can only be formed on the basis of incomplete information within the bounds of known reality. Abstract thinking does not exist. 
Actual idealism initially began as the "philosophy of fascism". Giovanni Gentile used his theory to support the formation of Mussolini's fascist state in Italy.
