As always, philosophy is the science of definitions. A philosophical writing, long or short, must include definitions of main concepts so analysis can be possible.
Intelligence is the ability to learn or understand or to deal with new situations. It is the synonymous of reason and logic. Intelligence is also applied to animals, plants, and technological objects (think of smart phone for example).
For a long tradition inherited from Christian catechism, intelligence is referred to as a moral value: an intelligent person is an ethical person; a bad person is not intelligent but clever and cunning. Which leads us to the following question: so a bad person, for a example a criminal, can never be qualified as intelligent no matter how intelligent they can be?
In order to promote ethics, moral values and Good (which is not a bad thing), religions made of intelligence a moral value. However, in its definition, intelligence is cleverness, smartness and cunningness since it is the ability to deal with a situation.
Intelligence is only an intellectual capacity, hopefully to be used for the good of humanity.
