列子生平简介
列子，名御寇，战国前期思想家，郑国人。思想上崇尚虚无飘渺，生前被称作“有道之士”。古书中有他卸风而行的记载，这是他潇洒的一面。然而现实中的列子则时常处于困顿之中。《庄子》中留下了这样的记载：子列子穷，容貌有饥色。
但他穷得非常有骨气。当郑国大官员派人给他送来粮食时，他坚决地辞而不受。
列子的来历：列子也称列御寇，或称列圄寇，是战国时早期道家代表人物之一。《历世真仙体道通鉴》记述列子是郑国人，他居住在郑国四十年，无人知其是何人。《汉书》作者认为他生活的年代早於庄子，因此《庄子》书中记载了很多关於他的传说 。
修道：列子之学，本於黄帝、老子为宗。相传他曾向关尹子问道，拜壶丘子为师，后来又先后师事老商氏和支伯高子，得到他们的真传，而友伯昏无人。修道九年之后，他就能御风而行。《述异记》中说，列子常在立春日乘风而游八荒，立秋日就反归“风穴”，风至则草木皆生，去则草木皆落。《吕氏春秋》说：“子列子贵虚”。他认为“至人之用心若镜，不将不迎，应而不藏，故能胜物而不伤”。列子穷而面有饥色，但拒绝郑国暴虐的执政者子阳馈赠的粮食。其弟子严恢问之曰：“所有闻道者为富乎? ”列子曰：“桀纣唯轻道而重利是亡！”他认为应摆脱人世间贵贱、名利的羁绊，顺应大道，淡泊名利，清静修道。
著作与成仙：列子著书有旧本二十篇，多寓言。刘向去其重复，存者八篇，号曰道家。道家者，秉要执本，清虚无为，及其治身，务崇不兢，合於六经元号列子书曰冲虚至德真经。唐玄宗天宝年间诏封为“冲虚真人”，宋宣和加封列子号为冲虚观妙真君。
《列子》相传战国时郑人列御寇所作。原书已亡佚，现在流传的本子是东晋张注的。这部分的内容丰富复杂，有消极无为、个人享乐的观点，也有包含朴素唯物论和辨证的观点。书中保存了不少先秦时代的寓言故事和神话传说，如《愚公移山》、《歧路亡羊》、《人有亡者》、《杞人忧天》、《齐人攫金》等。
