However, for those who haven't read or understood it, do not rush to accuse the author of dementia. <em>Pure Being<\/em> \u2014 this is a basic concept in Hegel's logic meaning that some object is, please do not confuse it with the existence of the object; the object may not exist in reality, but if we somehow defined it in our logic, it is there. If you think about it, indeed such things as <em>pure being<\/em> it is impossible to give a definition, and any such attempt will result in you simply referring to its synonyms or antonyms. <em>Pure Being<\/em> so abstract a concept that it can be applied to absolutely anything, including itself. In some object-oriented languages, there is an ability to represent everything as an object, including operations on objects, which essentially gives us such a level of abstraction. However, in programming, there is no direct analogy to <em>pure being<\/em> . To check the existence of an object, we need to check its absence.<\/p>\n<p><\/p>\n<pre><code class=\"cs\">if(obj != null);<\/code><\/pre>\n<p><\/p>\n<p>It\u2019s strange that such syntactic sugar is still missing, considering that this check is quite popular.<\/p>\n<p><\/p>\n<h1 id=\"nichto\">Nothing<\/h1>\n<p><\/p>\n<p>As you might have guessed <em>nothing<\/em> is the absence of anything. Its analog could be NULL. It is worth noting that in science, logic <em>nothing<\/em> is <em>pure being<\/em>, because it also exists. This presents some difficulties; we cannot refer to NULL as an object in any language, though in essence it is also one.<\/p>\n<p><\/p>\n<h1 id=\"stanovlenie-i-momenty\">Becoming and Moments<\/h1>\n<p><\/p>\n<p><em>Becoming<\/em> is the transition from <em>nothing<\/em> downward API support (simultaneously with this in <em>being<\/em> and from <em>being<\/em> downward API support (simultaneously with this in <em>nothing<\/em>. This gives us two <em>moments<\/em>, the first is called <em>emergence<\/em>, and the second <em>passing away<\/em>. <em>Passing away<\/em> is called so instead of disappearance because the logical entity cannot essentially disappear unless we forget it. <em>Elimination<\/em> This can be referred to as the assignment procedure. If we initialize an object, it occurs <em>at the moment of occurrence<\/em>, and in the case of assigning another value or NULL <em>the moment of disappearance<\/em>.<\/p>\n<p><\/p>\n<pre><code class=\"cs\">obj = new object(); \/\/occurrence\nobj = null; \/\/disappearance<\/code><\/pre>\n<p><\/p>\n<h1 id=\"nalichnoe-bytie\">Actual being<\/h1>\n<p><\/p>\n<p>In brief <em>actual being<\/em> \u2014 refers to an object that lacks a clear definition yet possesses <em>specificity<\/em>. What does this mean? A canonical example is an ordinary chair. If you attempt to give it a precise definition, you will encounter numerous difficulties. For instance, you might say: 'it is a piece of furniture designed for sitting', but an armchair is also created for this purpose, and so on. However, the absence of a clear definition does not prevent us from identifying it in space and using it to convey information about it, because in our minds, there is <em>specificity<\/em> the concept of a chair. Perhaps some have already guessed that to distinguish such objects from the data stream, neural networks were created. A neural network can be defined as a function that determines this <em>specificity<\/em>, but there are no types of objects that would include both clear and unclear definitions at the same level of abstraction.<\/p>\n<p><\/p>\n<h1 id=\"zakon-perehoda-kolichestvennyh-izmeneniy-v-kachestvennye\">The law of transition from quantitative changes to qualitative changes<\/h1>\n<p><\/p>\n<p>This law was formulated by Friedrich Engels as a result of interpreting Hegel's logic. However, it can be plainly seen in the first volume in the chapter about <em>measure<\/em>. Its essence is that <em>quantitative<\/em> changes in an object can affect its <em>quality<\/em>. For example, we have an object, ice, which when accumulating heat will turn into liquid water and change its <em>qualities<\/em>. To implement such behavior in an object, there exists a design pattern called 'State'. The emergence of such a solution was caused by the absence of something in programming like <em>the basis<\/em> for <em>for the emergence<\/em> of an object. <em>The basis<\/em> determines the conditions under which an object can arise, and in the algorithm, we decide when we need to initialize the object.<\/p>\n<p><\/p>\n<p><strong>PS:<\/strong> If this information is interesting, I will
