Passage One
The Internet is changing the way society communicates, processes information and knowledge. Some of these developments are exciting and challenging, but in one particular sense the Internet creates a fundamental challenge to the way humans interact.
Today, Internet dating has become more or less accepted as a way of forming relationships. There has been some criticism, but it has usually been of the functional and operational(操作上的) kind, regarding membership costs or users providing false pictures or information. There has been little thought or comment on why matchmaking websites by itself might be a bad thing.
Online matchmaking is conditioned on the idea of making rational choices. Internet dating is like shopping at LoveMart. We watch and read the adverts (people's profiles) and we then, make a rational decision to try the product. The more choices we have, we are told, the better for making the choice.
Furthermore, the way dating websites calculate(计算) matches distorts(扭曲) the very core of interpersonal relations. Online seekers of partners and friends rely on computer calculations of a set of hard questions. The questions that many of these websites use are so terrible ("Are you happy with your life? A. Yes, B. No, C. Most of the time") that they cannot reflect real conversations. THIS is not human interaction; it is a fundamental shift. Interpersonal relationships are being shifted into products that can be (supposedly) objectively measured and objectively chosen, even though such relations represent the exact opposite.
In his book, Alain Badiou noted love ---this great irrational driver of humanity---has become an object, which people wish to be fully informed about, choose rationally, and not suffer any unexpected disappointments from. It is, as philosopher Slavoj Zizek has noted, like caffeine-free coffee.
Some critics have suggested that online dating is taking society back to a pre-modern version of arranged marriages. I would say it is worse. It has taken over the very essence(实质)of what it means to be human.
