One could examine anxiety for a long time without thinking at all about nervousness. You will immediately understand me when I talk about this form of anxiety as objective anxiety as opposed to neurotic anxiety. Real anxiety or fear, therefore, appears to us as a very natural and logical thing. We should call it a reaction to the perception of an external threat, an anticipated insult that one expects and foresees. It is linked to the reflex of fleeing and can be considered an expression of the instinct for self-preservation. The opportunities for this, that is, the objects and situations that provoke anxiety, will clearly depend greatly on the knowledge and sense of power that this individual has regarding the external world.
