Sensations, perceptions, representations.
The sense organs are a kind of channels or windows open to the world, through which streams of external influences continually come in.
Sensations have a broad range of modalities, including tactile, visual, auditory, vibrational, temperature, olfactory, and gustatory. A type apart are sensations of processes occurring in the organism's inner environment —organic sensations, as well as sensations of the movements and positions of the body's organs, the sense of balance, and static sensations.
Representation is the highest form of sensuous reflection, it is imaginal knowledge about objects that are not directly perceived. The physiological condition of the existence of representations is retention of the traces of past influences and their actualization at the given moment. This function, which ensures the continuity and succession in cognitive activity, is termed memory; without it, recognition would be impossible. Representation is a generalizing synthesis of many sensuous perceptions.
Thought: Essence, Levels and Forms
Transition from sensation to thought. Only a small part of what man cognizes can be covered by sensuous contemplation. Mostly, cognition is realized in thought in terms of concepts, judgements, etc. Man cannot live without thinking. So how is the transition from the sensuous to the conceptual level of cognition to be explained? How is a sensuous image of an object transformed into an act of thought.
The specifics of thought. Thought is the highest form of rational cognitive activity. Thought is goal-directed, mediated, abstracted and generalized reflection of the essential properties and relations of things and phenomena realized in terms of concepts, judgements, and theories, and also it is a process of creative production of new ideas.
The unity of the sensuous and the rational. Starting with sensations and perceptions, proceeding to representations, and rising to the higher levels of theoretical thinking, cognition emerges as a unified process closely connected with will and emotions.
The principal forms of thought. A form of thought is a definite type of its organization, a type of connection between the elements of its content. The principal forms in which thought emerged, developed, and is now implemented, are the concept, the judgement and the inference.
- The concept is a form of thought which reflects the essential properties, connections and relations between objects and phenomena in (heir contradictions and development; a thought-concept generalizes and singles out the objects of a certain class in terms of definite generic and specific features inherent in them.
Concepts acquire logical meaning only in judgements. The judgement is a form of thought in which something is asserted or refuted through establishing links between concepts.
