 ## Informational models and their singularity
 To start with, let's define information. Information is an abstract concept of data provided by an object. 
 
-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.
+First things first, perception is an **ability to receive output from the outer world**. Inherent to living creatures, of course, as far as we know, rocks do not react on stimuli, otherwise they would be considered living.
 
-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**.

+### Sentience
 Nevertheless, those living creatures who are **sentient**, i.e. **able to sense**, perceive the world *differently*. Each species have their own **knowledge of the world** -- their own **worldview**, defined by the set of **perceptional abilities** available for them. 
 
 > Note: A model of **cognised environment** is called [**umwelt**](https://en.wikipedia.org/wiki/Umwelt), and an umwelt is consistent of [**qualias**](https://en.wikipedia.org/wiki/Qualia) - instances of **subjective experience**.
