Anу оldеѕt forms of fastenеrѕ tо the mеtаl іs ѕtill uѕеd tоday іs a rivet. Thе humblе rіvet hаѕ ѕeen ѕеrvice thrоugh twо world warѕ іn thе соnstruсtion оf shірs and аirсrаft, but ѕtіll tо thіѕ dаy thеre iѕ no modern rеplaсemеnt.

The Narcissist and Self-Loathing

-

In the comments section of the post on self-esteem vs. self-respect I made this statement, I have been witness to both. I have seen what were obviously real periods of self-loathing by Ns. I have also seen the theatrical versions. The "feel" of the fake version is quite different to the observant witness. I was asked to explain the difference between the faked self-loathing and the real demonstrations. I will try. First, it is important to not mistake a malignant narcissist's self-loathing as being connected with remorse. Do they have regrets? Oh, yes. But not for your sake. Only for their own sake. They only regret not getting what they think they deserve. Sam Vaknin, the most verbose of narcissists, contends that narcissists are, "immersed in self-loathing and self-pity. He is under duress and distress most of his waking life." Ref . Cry me a frakking river. Life is tough when you're always on the run from reality. If you read Vaknin...

To the Narcissist "There is No Good and Evil"

-
"There is no good and evil, there is only power, and those too weak to seek it..." Harry Potter and the Sorcerer's Stone . Those words are coming from the character whose mind is controlled by the evil character Lord Voldemort in the popular children's book referenced above.

They have constructed a view of reality which enables them to operate as they please while avoiding such sticky labels as "evil". It is important to understand how evil people skirt the whole issue of evil by reducing every human interaction to power...those who are strong enough to take it and those who are too weak to take it. This philosophy is often called the "law of the jungle" an...

The Malignant Narcissist

-
or....that word "malignant" is just another word for evil If someone knows the difference between right and wrong but persistently chooses to do wrong, to cause harm, to injure, to kill (the body or soul), we can safely assign to that person the term evil . Because this is my blog, I'll elaborate. The concept of evil has been around as long as humanity has. You may choose to believe it doesn't exist, but you would have to be either 1) a uniquely oblivious person or 2) evil yourself. (A convenient dodge for evil people is to do away with the term and they suddenly are free of exposure.) For the rest of you who are able to conceive that evil does exist, let's look at the concept as it relates to the malignant narcissist. Among the various definitions of evil we find this one: adj. : having or exerting a malignant influence All the definitions of evil apply to the malignant narcissist, but let us focus on this one. Let's look at the word "malignant"...
