Human body and the Ship of Theseus paradox/El cuerpo humano y la paradoja del barco de Teseo



According to Greek legend Theseus returned from Crete on his ship after having defeated the famous Minotaur and the Athenians kept the ship for centuries, replacing the damaged parts with new ones, over the years the Greek philosophers considered the paradox of whether the Theseus' ship remains the same after all the parts have been replaced.

Según la leyenda griega Teseo volvió de Creta en su barco después de haber vencido al famoso Minotauro y los atenienses conservaron el barco durante siglos reemplazando las partes que se iban dañando por otras nuevas, pasados los años los filósofos griegos se plantearon la paradoja de si el barco de Teseo sigue siendo el mismo después de haber sustituido todas las piezas.

This paradox is applicable to the same extent if we refer to the human body in which most of the cells that form it regenerate several times in the span of a human life, with the exception of female sex cells and neurons according to the majority of the authors, although not all agree.

Esta paradoja es aplicable en la misma medida si nos referimos al cuerpo humano en el que la mayoría de las células que lo forman se regeneran varias veces en el lapso de una vida humana, a excepción de las células sexuales femeninas y las neuronas según la mayoría de los autores, aunque no todos están de acuerdo.


The cells that last the least are those of the intestine that are completely renewed after a duration of between 2 and 4 days as well as the cells of the immune system that last between 2 and 10 days, followed by the lung cells that regenerate approximately every 8 days and skin cells that last between 10 and 30 days.

Las células que menos duran son las del intestino que se renuevan totalmente tras una duración de entre 2 y 4 días al igual que las células del sistema inmune que duran entre 2 y 10 días, seguidas de las células pulmonares que se regeneran cada 8 días aproximadamente y las células de la piel que duran entre 10 y 30 días.

Red blood cells, blood cells responsible for transporting oxygen throughout the body, are renewed every 4 months while those of the liver last between 6 and 12 months, the cells that make up bones and muscles are the longest-lived and take time to renew 10 and 15 years respectively.

Los glóbulos rojos, células sanguíneas encargados de transportar el oxígeno por todo el cuerpo se renuevan cada 4 meses mientras que las del hígado duran entre 6 y 12 meses, las células que conforman los huesos y los músculos son las mas longevas y tardan en renovarse 10 y 15 años respectivamente.


In short, after 15 years all the cells in our body have changed, some of them repeatedly, if we take into account a life expectancy of about 75 years, it turns out that we have changed all our components 5 times, so we can not say that we are the same person as 15, 30 or 45 years ago.

En definitiva que después de 15 años todas las células de nuestro cuerpo han cambiado, algunas de ellas repetidas veces, si tenemos en cuenta una esperanza de vida de unos 75 años, resulta que hemos cambiado 5 veces todos nuestros componentes, por lo que no se puede decir que seamos la misma persona de hace 15, 30 o 45 años atrás.

In the same way that the Greeks philosophized with the paradox of the Perseus ship and if it was still the same ship that left for Crete, if our body is also totally renewed every so often, what then does the identity of a being that changes continuously over time consist of? . Think about it.

De la misma forma que los griegos filosofaban con la paradoja del barco de Perseo y si seguía siendo el mismo barco que partió a Creta, si también nuestro cuerpo se renueva totalmente cada cierto tiempo, ¿en que consiste pues la identidad de un ser que cambia continuamente con el tiempo?. Piénsalo.

Hola @mauromar, Genial somos unos frankenstein a nivel celular.

Que tal @mauromar, podríamos decir que la identidad solo busca clasificar la singularidad de cada uno de nosotros.

I like reading all of your articles, like the ship was wrecked, but they just fix it with a new one.
Maybe the ship did not want to be replaced, because the quality was so great it lasted.

Thank you for sharing.

The Human Body You get a new suit of skin every month and a new liver every six weeks.

We each have different bodies and can say that every person is identified with their body. By postulating that a human being is their body, we are subject to the same insoluble questions that we faced with the ship of Theseus and other physical objects.

The Ship of Theseus was an ancient Greek paradox. Over time, every plank and mast in the ship was replaced, yet it remained the same ship. That is almost true of the human body. Only one part of your body is as old as you are.

Your post is very knowledgeable, everyday learning new things, another new things learn about red blood sell.
Thanks to share.
