山东农业工程学院学报2016年第33卷第2期0.前言在西方文学史上，爱伦·坡是不可不提的重要人物之一，他在文学史上画上浓墨重彩的一笔，为后人留下大量经典著作。
在19世纪，当批判现实主义的风头日显炽烈，浪漫主义的余威尚未消减，在这样的形势背景下，爱伦·坡创造了独属于自己的创作舞台，他别出心裁地将人的主观世界作为创作对象，标志着文学创作将进入以刻画人类心灵世界为主的时代中。
毋庸置疑，人类心灵世界最具复杂性，将其作为创作对象，可以为读者带来了一种全新的体验。
1.《黑猫》简介《黑猫》的故事情节十分简单，但是在细细品读之后又能得到另一番感受，整篇小说的的字里行间都是以刻画男主人公的内心世界为主。
在主人公年轻时，他崇尚善念，他热爱小动物，关心它们，呵护它们，他通过自己的善行对内心的邪念进行压制，所以为我们呈现出一个可亲、和蔼的人物形象。
但是后来，主人公开始酗酒，他的理智力量逐渐被邪念所瓦解，他对自己的妻子拳打脚踢，对自己的宠物不管不问甚至尽情虐待，他善良的本性开开始被酒精所麻痹，逐渐变成了一个不折不扣的恶魔。
后来，他杀死了自己的妻子，并将她封在了地下室的水泥墙中，但仍旧被警察发现。
最后，主人公在一种深切的懊悔与自责中走向了绞刑架，付出了生命的代价，这种结局在意料之中，却也引人深思。
从宏观角度而言，爱伦·坡在《黑猫》中为我们展现了一个人的精神世界从好变坏的蜕变过程。
一开始，男主人公以善为主，具备强大的理智力量，但由于酒精作祟，仍旧被隐藏于内心的邪念所击败。
作者在这本小说中为我们呈现了人类心灵世界中的多重内容，使人印象深刻，欲罢不能。
2.《黑猫》的创作特色《黑猫》的创作手法别出心裁。
在以前，大部分作家都是以现实生活作为创作对象，力求形象地刻画社会图景，但是爱伦·坡不一样，他独树一帜将人类精神世界作为创作对象，探索人类心理的种种变化，使读者从故事中得到启发。
具体而言，《黑猫》的创作特色体现在以下几点：2.1采用第一人称叙述手法在《黑猫》这本小说中，爱伦·坡没有用第三人称叙述手法，通过以“我”的口吻展开叙述，给读者带来一种强烈的代入感。
