There's an idiom that says "seeing is believing", but seeing is also not reality-whether it's a prehistoric cave painting or a pornography, in which celebrity faces have been pasted onto the writhing, naked bodies of adult actors.The seeing is constantly being deceived. In the past, visual deception has been widely used in art. In the 17th century, the french audiences were bewitched by trompe-l'oeil, a realist-painting technique in which objects seem to emerge from the frame.Baroque churches are famous for their ceiling frescos that lift the pious gaze into the heavens. Nowadays, virtual reality has promised visual deception inappreciable, and the emergence of "inception" has made dreams "close to" reality.Increasingly realistic imaging techniques have led to the idea that science& technology can bend reality.

The question is "Can  science& technology  bend really reality"?If science& technology can bend reality, what is reality?

"Reality" is a contradiction and unity -- science and technology originated in the objective material world, and it is human's "knowledge" of the objective material world that creates science and technology. In turn, science and technology have helped mankind to transform the objective material world, indirectly promoting its own development.

To a certain extent, science & technology can transform reality, maybe it is more technology that bends the appearance of reality than its essence.

有成语讲“眼见为实”，其实眼见也未必为实——无论是史前的洞穴画，还是PS名人面孔的色情片，人的眼睛一直都在被欺骗。在过去视觉骗术一直都被广泛地应用在艺术领域，17世纪的法国人民可能被错位画迷乱了眼睛，虔诚的教徒也曾真情或假意地相信巴洛克教堂的穹顶即是天堂。如今虚拟现实技术让视觉骗术已成小儿科，“盗梦空间”的出现已经让梦境“趋近于”现实。越来越逼真的成像技术使得有关“科技扭曲现实”的观点渐渐浮埃尘上。

问题是“科技扭曲的真的是现实”吗？如果“科技能轻易扭曲现实”，那什么又是“现实”？

“现实”是矛盾与统一——科技起源于客观物质世界，是人类对客观物质世界的“见识”创造了科技。反过来，科技又帮助人类改造了客观物质世界，间接的推动了自身的发展。

一定程度上，科技是能改变现实，也许呈现更多是科技扭曲了“现实的表象”而非其“本质”。
