Consciousness, thoughts, and emotions are all manifestations of electrical activity in the brain. To believe that they continue after death is like believing that your browser continues to run after you turn off your computer.
Your statement brings to mind the story of the doubting Thomas, who did not belive that Jesus had been resurrected until Jesus Himself showed him His wounds.
Believe or don't believe in any sort of an afterlife as you wish. If you don't believe in an afterlife, at least have the decency not to try to convert those of us who DO believe in an afterlife over to your view.
IMO, the point of the article is not so much that some of those who follow Judaeism don't believe in an afterlife.
The article infers that NO Jew believes in an afterlife. The article, therefore, seems meant to incite hatred toward the Jewish population in general, thereby bringing the anti-"zionist", Jew hating crowds out of the woodwork. In that, the article seems to have succeeded.
In heaven the soul will not be required or have need to "think" on earthy terms... all that will be irrelevent perhaps. Using your analogy of the computer turned off : Even after my PC is turned off for the night, even after being unplugged... it continues to function, the time and date, for example are still being processed. Also you can think of the fact that data is still in storage on the hard drive to be brought back to use when turned on again. Perhaps the memory of some relevant information is not only implanted on the brain, but on the soul as well.
It is very interesting to me that intelligent human beings can reduce life down to mere electrical activities. Removing the divine from the physical has long been the goal of those who deny the divine. I am an educated person, but I am very happy that I have not been educated to the point where I would deny the divine.
The separating of the waters in Egypt to allow the Hebrews to escape is a good illustration of how people attempt to remove the divine from the physical world. They say that some physical event occurred that caused the waters to recede. I believe that one idea is that an earthquake occurred. These people cannot look beyond the physical to see the hand of God working. Even if an earthquake did occur, did it happen without design? Was it just plain dumb luck for the Hebrews? I would not think so. But those who would deny the divine would say yes.
