Abstract
The study analyses three strategies considered as tools in human thinking - appropriation, restriction and cassation. The starting point is the assumption that the nature of the intelligence is to found in processes by which the human thought reacts when confronted with elements that bring a challenge for the schemata previously formed in real social circumstances.
Author's critical insights attempt so show how the three strategies of intelligence has been considered from philosophical perspectives, and, at the same time, how these strategies operate in social process.
