2．人工智能、信息及其對意識論的深化現(xiàn)代科學(xué)的發(fā)展，特別是以信息論、控制論、電子計算機科學(xué)和腦科學(xué)相結(jié)合為理論基礎(chǔ)的人工智能技術(shù)的發(fā)展，進一步證明了辯證唯物主義關(guān)于物質(zhì)和意識的相互關(guān)系的原理，也給這種現(xiàn)代唯物主義提出了需要深入探索和解釋的許多哲學(xué)問題。在這些問題之中，人工智能和信息尤為重要。人工智能是相對于人的自然智能而言的。所謂自然智能，是指人所特有的自覺的意識能力，特別是抽象思維能力。由于這種能力是人的一種天賦，所以將其稱為人的自然智能。所謂人工智能，則指憑借電子計算機所實現(xiàn)的對人的某些智能的模擬，通過這種思維模擬，使人的某些智能得以再現(xiàn)和放大。自從電子計算機在20世紀(jì)中期問世以來，其作用越來越廣泛，模擬功能越來越強，更新?lián)Q代越來越快，對生產(chǎn)和社會生活的影響也越來越大。自50年代中期開始，人工智能便以計算機作為主要的支持手段，逐漸發(fā)展成為一門新興的科學(xué)技術(shù)。
