+## Informational models and their singularity
+To start with, let's define information. Information is an abstract concept of data provided by an object. 
 
-### Reality is a set of objects with stated properties
+An object is a conceptual unit of objective reality -- a conceptional model consisting of facts that define everything embedded in the universe.

+## Cognitive models are plural

+Ability to receive information is called perception -- **ability to receive output from the outer world** inherent to living creatures.
 
 The complexity of reality made carbon-based lifeforms diverse that much so it's hard to believe that all inhabitants of Earth **share the same nature**. Bacteria, insects, fish, cats, humans, corals, pine trees and mushrooms - all living creatures are made of the same elements by the same rules and live **in the same world**.

 The situation is different for species of *other* classes, those with different kinds of **receptive cells**, and, therefore, **sensory organs**. 
 
 For examples, **insects** are able to **sense humidity** by a completely different perception than humans. Humans decide whether they are wet or not based on the feeling of temperature difference between their skin and the environment. Insects *just* feel wetness -- by *hygroreceptors* - specific **sensory cells**.
