Levels of abstract intelligence
Yakov Feldman's theory describes 8 stages of cognitive complexity, from concrete objects to global universals.
Object
I can feel the thing, therefore it exists
Cognition is focused on the physical tangibility of the surrounding world. Perception is anchored in material properties: shape, weight and texture. Abstract reasoning feels alien when it cannot be checked by the senses or applied to a concrete object right now.
Action (Relation)
I act in the moment, therefore I am connected to reality
Attention shifts from objects themselves to their direct interaction. Reality is perceived as a continuous flow of contacts, movements and responses. Thinking is strongly situational and helps the person orient quickly in changing circumstances.
Algorithm
I follow the steps, therefore I am protected from chaos
Space begins to be organised through strict sequences. The intellect relies on lists, rules and procedures, trying to protect itself from uncertainty. Thinking proceeds linearly from cause to effect and values predictable results.
System
I see the structure, therefore I understand the whole
A qualitative shift occurs from linear perception to structural vision. Separate elements lose their self-contained value and become parts of a more complex architecture. A situation can be understood only through its links, nodes and dependencies.
Parameter
I measure, therefore I optimise
The systemic view is supplemented by quantitative measurement and optimisation. Attention turns to how efficiently a structure works under limited resources. Thinking analyses metrics, variables and the balance that produces the best return.
Principle
I find the law, therefore I understand the essence
The diversity of systems and parameters is reduced to the search for a fundamental basis. The intellect peels away situational details in order to reveal the hidden law that explains the nature of the phenomenon.
Paradox
I hold the contradiction, therefore I think beyond formal logic
The mind can hold mutually exclusive concepts without forcing them into a simple compromise. Thinking moves beyond formal logic and recognises that truth may be hidden inside contradiction, conceptual rupture and dialectical development.
Universe (Infinity)
I see unity of all things, therefore I think beyond disciplines
This is the highest degree of cognitive abstraction, where boundaries between disciplines dissolve. The intellect operates with categories of unity, seeing local processes as manifestations of broader cosmic or philosophical patterns.
