快乐取决于心态

佟晨绪

 ①那天在书店看到一本米勒博士和米尔博士著作《快乐是一种选择》的书,翻来看了很久,书中从多种角度阐述了快乐对于人生的重要性,从多个方面告诉我们,人要想获得快乐,就应该抱有种淡看云卷云舒、庭前花开花谢的超脱心态。

 ②在这个细观瞬息万变、诱惑四伏的当下社会,为人处世正需要我们保持这种平淡沉稳的心态。斯宾诺莎曾说:“快乐是一个人从较小圆满到较大圆满的过渡;痛苦是一个人从较大圆满到较小圆满的过渡。如果我们选择紧紧抓住痛苦不放,那么快乐就永远不会到来。”

 ③其实我们都知道,快乐是我们的需求得到了满足,于里于外表现出的一种正常回应;是没有钱财多或少的定位;没有房屋面积大或小的标准;没有职位高或低的标尺衡量;没有春夏秋冬的暖凉之分;没有男女老幼之别,更没有雅俗傲庸之辨。雅人有雅兴,俗人有俗趣。无论富与贫、官与民,都各有其乐。锦衣玉食也好,粗茶淡饭也罢,这些都是为心性满足而快乐。

④快乐在某种程度上是一种洒脱的人生境界,是一种积极乐观的生活态度。但并非人人都能做到洒脱自如,有的人过于拘谨就无法洒脱,有的人过于张扬自我不懂洒脱。其实,洒脱应该是那些不以物喜、不以己悲,顺境不高傲、逆境不萎靡豁达的精神境界。形象地说,洒脱就是一桌风味各色的佳肴,酸甜苦辣涩俱全。如果我们不会品味与享受,就体会不出佳肴的独特风味所包含的幸福快乐,更体会不出人生多姿多彩的美好况味。

⑤古今名人中,能真洒脱者大有人在,唐朝有诗仙之称的李白因小人进谗而“赐金放还”。一友人出于对这样一位天才被弃置的痛惜,于是不惜金钱设宴为他饯行。而面对金樽美酒、玉盘珍馐,诗人吟出了这样的千古名句“人生得意须尽欢,莫使金樽空对月。天生我材必有用,千金散尽还复来”的乐观诗句。那种不向命运屈服的抗争精神以及睥睨天下的洒脱傲气,使《将进酒》成为后人称颂的千古名篇。⑥诗人刘禹锡,因革新遭贬谪,但却不为那些压力所阻,仍然以顽强精神与政敌相抗争,写出“玄都观里桃千树,尽是刘郎去后栽”、“种桃道士归何处,前度刘郎今又来”。他以潇洒豪放的人生态度,超过“巴山蜀水凄凉地”,坚守“二十三年弃置身”的人格,最终迎来仕途上崭新的篇章。

⑦伟人有伟人的洒脱豪迈,百姓也有百姓的快乐。洒脱与快乐对于我这平常小人物来说亦是如此光鲜与壮美。面对繁杂而平淡的生活,以一种宠辱不惊、去留无意的洒脱飘逸去面对去感悟,不失为一种超然的快意。忙碌时,用一种独特的人文品格为事业迎来送往是快乐,用一双勤劳的手为家人洗手做羹也是快乐;闲暇时,捧一杯香茗,慢慢地品尝那淡淡的清香;捧一本书,慢慢吸取它的滋养;听一首乐,用情享受心灵天堂更是快乐!

⑧其实,快乐很实际,洒脱也很简单,它就藏在我们生活中的每个细节,只要我们用心去发现、去选择、去感受,就会时时体味到那份快乐的滋味。毕竟,世上没有绝对幸福的人,只有不肯快乐的心。                     (选自《思维与智慧》,有删改)

阅读理解。

     Parents are often amazed at how fast their child grows and develops. New research has determined

that the ability to quantify may develop much sooner than most parents realize.

     Kristy vanMarle, professor of the University of Missouri, has determined that contrary to what

previous studies have shown, infants (婴儿)are able to quantify substances (物质)-like sand or water-as

early as 10 months. As long as the difference between the two substances is large enough, infants will

choose the larger amount, especially when it comes to food.

     With the assistance of her team researchers, vanMarle tested the quantifying skills of babies by

presenting them with two cups: one containing a small amount of food, and one containing a larger

amount. Consistently, the babies chose the larger amount.

     "Several studies throughout the last 15 years have shown that infants are very good at telling how

many objects they see; however, infants don't seem to count things like water or sand," vanMarle said.

"What we're saying is that they can quantify substances; it's just much harder. The infants can see how

much food goes into each cup and compare that in their memories. They decide which amount is larger,

and they almost always select the larger one."

     This information further refutes (驳斥) the long-held idea that babies "know nothing of the world,"

vanMarle said.

     "Since psychologists have begun studying infants with sensitive measures, we've discovered a lot of

early abilities. I think for parents, it should be exciting to know that there's somebody in there that has

some fundamental and basic knowledge of the world, and that knowledge is guiding their development,"

vanMarle said.

     In the future, vanMarle says this kind of study could be linked to a child's progress in math-related

skills, although programs marketed to increase those abilities, such as "Baby Einstein," still have mixed

reviews when it comes to academic study.
