Why do vampires need blood?
One thing that is a main key to the definition of a vampire is there need for blood. But what many of us as readers and watchers do not think about is why they have a need for blood. The answer to this can differ depending on whom you speak to. In my opinion, though, I agree with what I have read in a book by Augustus Montague Summers entitled, The Vampire, his Kith and Kin.
In this book he states, “for he (vampire) is a thing which belongs to no world at all; he is not a demon, for the devils have a purely spiritual nature, they are beings without any body…” Vampires are creatures that attack those that are sleeping at night and suck out all of the blood from their bodies to destroy them. The reason that they take the blood is because they crave blood to obtain sustenance for their own body.
So what is it that makes the blood the essential need of a vampire to keep on “living”? Well, it is expressed in the Chinese culture by writers in medicine, while thought by the Arabs, and very prominent among the traditions of the Romans that, “even with regard to animals the soul or life of the animal was in the blood, or rather actually was the blood” (The Vampire, his Kith and Kin page 18).
More evidence of this belief is brought to us by the Bible where it as been said that “Because the life of the flesh is in the blood” the word life also signifying the word soul in the Hebrew language. This can be found in Leviticus xvii.
It is believed and kept in the tradition of most vampire writers that a vampire does not have a soul. When we bring this into the equation one can now be able to solve the equation. A vampire seeks out to vitalize and rejuvenate his own dead, soulless, body by draining a human, soulful, person of their blood and therefore regaining a sort of soul or essence for a short period of time.
Because of this I come to the conclusion that a vampire is not able to keep this soul that is not his or hers in their body for any long period of time and this is why they continue to need blood and feed off of the living. The living that have souls, which are in their blood, and can provide them with sustenance for a night until they awake again and repeat the process all over again.
If this were all to be true my question would be: do vampires have a soul after sucking the blood of a human? Is this why some vampires have more feelings in certain books than in others?
What do you think? I would like to hear the opinions of others to find out if this is what most people would believe and agree with.
