can i use a us shaver in europe ?

yes, but you need to check the input voltage on the label of the shaver. most are 100-240v so it will accept the input ok. the other issue is the type of plug it has on it. depending whether it is a rechargeable or just plain mains-only shaver it will probably have a two pin plug. if the pins are round, they will fit into any bathroom shaver socket. if they are flat, they are designed to go into a regular wall socket, so you will need a travel plug for the country you are travelling to.

<<>> most shavers are able to use 100-240 v but they have an adjustment which must be set to the new voltage when you change country. my shaver can be switched to 110 v, 120 v , 220 v and 240 v and if it is connected to the wrong voltage it might not work and/or it might be damaged.

why does literature exist ?

why does literature exist?

i would love to start by citing two antiquities that sought to unravel the birth of literature: plato and aristotle.

plato said that idea is the ultimate reality. he would say that art is bad for the reason that it takes away twice the reality of life. this is based from the theory called mimesis that art is an illusion of reality and of the truth.

aristotle deliberately defended his own beliefs and teachings as opposed to his mentor, plato. he argued that art is not an illusion of reality but rather a vector to better understand life and its meanings. an artist might imitate a table crafted by a carpenter as a product of human idea but an artist may put symbols and meanings that are absent in the real world. art is not an imitation but rather a reflection of an artist's creative idea ought to touch us and open our hearts to appreciate the real world.

now, let me give my definition of literature.

it is an art.

it is a story of every man's life.

it must be a vehicle in telling the truth.

it is life itself.

again, why does literature exist?

it exists because of us. literature can not continue its role in the world without its advocates. literature can not be opened without a rational being. it existed because of us. legends, tales, poetry and etc., it is all human initiative. consequently, literature was born in the same time humanity was born as well.

remember that we die twice. first is when the soul departs from the body and second is when the last person in the world stops mentioning or remembering our name; only by then, we will long be forever forgotten and death came to us.
