When Satan is not influencing people through blatant idolatry or fear of spirits, he controls them through false ways of thinking which lock them in spiritual darkness. The Apostle Paul mentions this kind of bondage when he talks about —
We destroy every proud obstacle that keeps people from knowing God. We capture their rebellious thoughts and teach them to obey Christ. – 2 Corinthians 10:5
Paul uses the Greek word hupsoma, which is translated as ‘pretension’ or ‘high thing’.
“It is obvious from the context of 1 Corinthians 10:4 that these strongholds are not demons or geographical locations* but psychic habitats. It is from these “head nests” that Satan and his cohorts endeavor to manipulate our inner world. The word arguments, often translated imaginations, is an interesting one. Taken from the Greek word logismos, it is defined more precisely as ‘calculative reasonings over time’ (as opposed to random occasional thoughts). This definition makes these arguments or imaginations look more like what they almost certainly are — religious or philosophical systems.” — George Otis, Jr. Twilight Labyrinth, p. 281
