  This study is a contribution to basic research on narcissism shown on addic
  tive behavior. A new biosystematic model of narcissism underlying addictive 
  behavior is outlined. Basically, normal narcissism is defined as the self-reference of living systems maintaining their circular organization and identity. The communication between narcissistic systems follows the narcissistic logic of fitting or non-fitting of structures (a third possibility is excluded) shown on geometric diagrams. From this model of narcissistic interactions with the environment, addictive behavior is deduced. If the narcissistic desire for the ideal objects cannot be satisfied in the environment, the narcissist attempts to cope with this lack of intended objects by abuse of addictive substances. This leads to an overexpression of receptors in pertinent brain areas that may underly craving on the behavioral level, interpreted as pseudo satisfaction of narcissistic desires
  —destiny becomes an addiction. In conclusion, the significance of the biosystematic model of narcissism for the understanding of addictive communication and the psychopathology of depression is briefly discussed.

Introduction</title><p>The concept of narcissism introduced by Freud [<xref ref-type="bibr" rid="scirp.111349-ref1">1</xref>] has been further developed by the psychoanalysts Kohut [<xref ref-type="bibr" rid="scirp.111349-ref2">2</xref>] and Kernberg [<xref ref-type="bibr" rid="scirp.111349-ref3">3</xref>] and psychologists most notably Millon [<xref ref-type="bibr" rid="scirp.111349-ref4">4</xref>] leading to the introduction of the diagnostic concept of the narcissistic personality disorder [<xref ref-type="bibr" rid="scirp.111349-ref5">5</xref>]. Current understanding of narcissism and narcissistic personality disorder is excellently reviewed by Yakeley [<xref ref-type="bibr" rid="scirp.111349-ref6">6</xref>]. The narcissistic personality disorder is characterized by personality traits of grandiosity and attention-seeking and significant impairments of personality functioning (e.g. perceive oneself as exceptional, persistent fantasies of success, looking excessively to others for the regulation of self-esteem [<xref ref-type="bibr" rid="scirp.111349-ref7">7</xref>]. Moreover, the narcissistic spectrum model integrates existing theories of narcissism characterizing narcissistic personality by self-importance, grandiosity and vulnerability [<xref ref-type="bibr" rid="scirp.111349-ref8">8</xref>].</p><p>Significantly, the basic criteria for substance use disorder [<xref ref-type="bibr" rid="scirp.111349-ref7">7</xref>] suggest parallels between narcissism and drug abuse (cravings to use the substance and tolerance) [<xref ref-type="bibr" rid="scirp.111349-ref9">9</xref>]. Similarly, Rogier and Velotti [<xref ref-type="bibr" rid="scirp.111349-ref10">10</xref>] found that gambling disorder is associated with grandiose narcissism and inability to regulate emotion, but not with vulnerable narcissism. Based on a literature review Laurence defined “narcissism as addiction to esteem, and addiction as a narcissistic pursuit” [<xref ref-type="bibr" rid="scirp.111349-ref11">11</xref>].</p><p>From an interdisciplinary, system-oriented point of view narcissism can be defined as organismic self-reference [<xref ref-type="bibr" rid="scirp.111349-ref12">12</xref>]. This concept has been further elaborated [<xref ref-type="bibr" rid="scirp.111349-ref13">13</xref>] [<xref ref-type="bibr" rid="scirp.111349-ref14">14</xref>] and introduced in my models of the psychopathology of mental or affective disorders [<xref ref-type="bibr" rid="scirp.111349-ref15">15</xref>] [<xref ref-type="bibr" rid="scirp.111349-ref16">16</xref>] [<xref ref-type="bibr" rid="scirp.111349-ref17">17</xref>]. The present paper outlines an elementary biosystematic model of narcissistic self-reference and communication, from which addictive behavior in the sense of insatiable narcissism can be deduced.</p></sec><sec id="s2"><title>2. Elementary Architecture and Function of Narcissism</title><sec id="s2_1"><title>2.1. Narcissistic Self-Reference and Communication</title><p>Abstract formulated narcissism is total self-reference [<xref ref-type="bibr" rid="scirp.111349-ref12">12</xref>]. According to C.G. Jung self-reference represents an archetypic system comparable to a snake biting in its own tail, called Ouroboros [<xref ref-type="bibr" rid="scirp.111349-ref18">18</xref>]. Let us suppose that any living system forms a virtual cycle that exists in an empty space and is only equipped with self-movement (<xref ref-type="fig" rid="fig1">Figure 1</xref>).</p><p>Suddenly, another self-cycling living system enters into the space so that the problem of communication arises (<xref ref-type="fig" rid="fig2">Figure 2</xref>). Since both living systems are self-referring systems, they obey the all-or-none logic of narcissism. Therefore, communication can only be realized, if one living system becomes incorporated by the other and vice versa. However, for the process of incorporation both virtual living systems (<xref ref-type="fig" rid="fig2">Figure 2</xref>) must be self-embodied with material.</p><p>Basically, for the distinction between the narcissistic systems each system must be endowed with a specific composition of material (<xref ref-type="fig" rid="fig3">Figure 3</xref>).</p><p>Since some structures of both systems are equal and others differ, the narcissistic all-or-none logic works on a mechanism of fitting or non-fitting (a third possibility is excluded). To realize these operations an evolutive process is necessary, in which the original cycle evolves to a sphere with many places of specific compositions (shown in <xref ref-type="fig" rid="fig3">Figure 3</xref> as geometric forms). In parallel, numerous living systems and objects in the environment evolve. In this situation, the original solitary narcissistic system is faced with the problem of communicating in a poly-ontological (consisting of many loci) world [<xref ref-type="bibr" rid="scirp.111349-ref13">13</xref>] [<xref ref-type="bibr" rid="scirp.111349-ref19">19</xref>] [<xref ref-type="bibr" rid="scirp.111349-ref20">20</xref>].</p><p><xref ref-type="fig" rid="fig3">Figure 3</xref> gives a simple example of self embodiment of two narcissistic systems (x, y) in the world of objects according to the logic of fitting or non-fitting.</p><p>Although the geometric composition of the two systems differs, they correspond to all objects in the environment. In this figure, two examples of incorporation of objects into the environment are depicted.</p></sec><sec id="s2_2"><title>2.2. Narcissistic Desire</title><p>Based on the key-lock principle living systems either accept objects or reject them with the intention to realize their desires [<xref ref-type="bibr" rid="scirp.111349-ref21">21</xref>]. However, normal narcissism, capable of communicating, comes to existential limits, if the environment lacks appropriate objects or a specific object cannot be found. A person in that situation feels out of place since his (her) desires cannot be fulfilled. We observed that these narcissistic personalities are at risk of committing suicide intending a radical “change of the place of existence” [<xref ref-type="bibr" rid="scirp.111349-ref22">22</xref>] towards an “appropriate” world (paradise). But depression or (and) addictive behavior mostly occur as abnormal coping strategies. Most importantly, such existential crises are basically caused by the aggravation of the narcissistic logic of fitting or non-fitting, since not only an appropriate structure (e.g. a sphere of any material), but also a suitable specific material (“the sphere must be golden”) is absolutely intended. <xref ref-type="fig" rid="fig4">Figure 4</xref> shows a graphic of the narcissistic desire for the “golden sphere” which does not exist in the environment. This drawing focuses on the many-places composition (different geometric figures) of the narcissistic Ego-system and the various objects in the environment. Note that all corresponding places of which the Ego-system is composed, exist in the environment, only the golden sphere cannot be found in the environment (yellow circle).</p></sec></sec><sec id="s3"><title>3. Pseudosatisfaction of the Narcissistic Desire in Addictive Behavior</title><p>Ultimately, the narcissistic Ego experiences that indeed spheres, suitable for</p><p>satisfaction of these places of desire is available in the environment (<xref ref-type="fig" rid="fig5">Figure 5</xref>). This means that non-golden spheres also fit in the “synaptic lock” imitating a golden sphere. Importantly, the experience of the seeming existence of the desired objects causes euphoria. However, sooner or later the narcissistic Ego realizes that the spheres are not golden. Disappointment and depression are the consequence.</p><p>To cope with this painful situation and to stay alive, the organization of the place structure of the narcissistic ego transforms by an increased generation of “sphere-places” (<xref ref-type="fig" rid="fig6">Figure 6</xref>). In this process, the quality of golden spheres is compensated by the quantity of non-golden spheres. An addictive hunt for euphoria</p><p>begins and never ends. In parallel, other types of objects, normally accepted in communication, become rejected. In this fashion, the communication of the addictive narcissistic personality increasingly narrows down to addictive substances. In essence, the spread out of “sphere-places” in the bio systemic model here outlined represents a pseudo satisfaction of the narcissistic desire—destiny becomes addiction.</p><p>Whereas a narcissistic person with depression experiences specific or even all domains of reality as inappropriate for the realization of his (her) desires, the addicted narcissist strives for substances, which imitate an appropriate environment. Indeed, these substances fit in the synaptic lock of the material equipment of his (her) brain but cause imbalances of glial-neuronal interactions in tripartite synapses of the brain. The brain reacts with an overproduction of receptors that are suitable for activation by addictive substances [<xref ref-type="bibr" rid="scirp.111349-ref23">23</xref>], but exert no constructive effects since addictive substances do not embody objects of the environment that are really intended by the narcissistic desire.</p><p>Basically, the increase of the number of receptors “craves satisfaction” by occupancy with addictive substances. This is the diabolic cycle of addictive behavior responsible for substance tolerance, loss of control and dependence [<xref ref-type="bibr" rid="scirp.111349-ref7">7</xref>]. In other words: the addicted narcissist lives in an illusionary world in danger of perishing from insatiability.</p></sec><sec id="s4"><title>4. Discussion and Conclusions</title><p>The significance of the biosystematic model of narcissism here proposed lies in the description of elementary structures on which normal and pathological narcissism operate. In general terms, narcissism is total self-reference formally described as a permanent rotating cycle. Maturana characterized living systems as self-referring systems circularly organized to maintain their identity [<xref ref-type="bibr" rid="scirp.111349-ref20">20</xref>]. Here we speak of a normal narcissistic organization [<xref ref-type="bibr" rid="scirp.111349-ref12">12</xref>] [<xref ref-type="bibr" rid="scirp.111349-ref13">13</xref>]. Note that the interactions of a narcissistic system with the environment (objects, subjects) follow exclusively the narcissistic logic of fitting or non-fitting structures shown on diagrams of geometric figures. Therefore, narcissistic systems either accept or reject objects of the environment to realize their desires [<xref ref-type="bibr" rid="scirp.111349-ref21">21</xref>]. This is the rationale of the model proposed that may underly the phenomenology of narcissism.</p><p>From this model of narcissistic interactions with objects of the environment, addictive behavior can be deduced. If narcissistic desire cannot be satisfied in the environment by intended objects, the narcissistic person tries to cope with the lack of intended objects by abuse of addictive substances. Though the ideal objects (“golden spheres”) cannot be found in the environment, “non-golden spheres” also fit in the receptor structures of the brain generating euphoria.</p><p>The relevance of neuroscience for the investigation of narcissism is reviewed by Di Samo and coworkers focusing on personality neuroscience for the development of a more complete view of narcissism [<xref ref-type="bibr" rid="scirp.111349-ref24">24</xref>]. Experimental investigations indicate upregulation of opioid receptors in response to repeated exposure to cocaine and ethanol, and the resulting opioid receptor upregulation may play an important role in craving [<xref ref-type="bibr" rid="scirp.111349-ref23">23</xref>]. Similarly, chronic nicotine abuse also upregulates nicotinic acetylcholine receptors throughout the brain and leads to nicotine seeking [<xref ref-type="bibr" rid="scirp.111349-ref25">25</xref>]. Together, the increase of receptors in the brain that may underly craving on the behavioral level can be interpreted as pseudo satisfaction of narcissistic desire so that desire becomes addiction.</p><p>Finally, it should be mentioned that the biosystematic model proposed outlines elementary mechanisms of narcissism prone to addictive behavior not only in substance abuse but also in intersubjective communication as in addictive use of social media [<xref ref-type="bibr" rid="scirp.111349-ref26">26</xref>] [<xref ref-type="bibr" rid="scirp.111349-ref27">27</xref>]. Narcissists crave affirmation from others like a physical addiction [<xref ref-type="bibr" rid="scirp.111349-ref11">11</xref>]. Admittedly, one may argue that this model is too abstract lacking the explanatory power of psychodynamic mechanisms. However, the more formal description of narcissism may stimulate basic research on addictive communication and on the psychopathology of depression [<xref ref-type="bibr" rid="scirp.111349-ref16">16</xref>].</p></sec><sec id="s5"><title>Acknowledgements</title><p>I am grateful to Christian Streili for designing figures and Marie Motil for preparing the final version of the paper.</p></sec><sec id="s6"><title>Conflicts of Interest</title><p>The author declares no conflicts of interest regarding the publication of this paper.</p></sec><sec id="s7"><title>Cite this paper</title><p>Mitterauer, B.J.
