I found the following from google and it is similiar to what my pastor once
stated in a Christianity history class, and similar to Charles Spurgeon's view.
"So, in the Calvinism vs. Arminianism debate, who is correct? It is
interesting to note that in the diversity of the body of Christ, there are
all sorts of mixtures of Calvinism and Arminianism. There are five-point
Calvinists and five-point Arminians, and at the same time three-point

Fundamentalists are sometimes horrified when the Virgin Mary is referred to
as the Mother of God. However, their reaction often rests upon a
misapprehension of not only what this particular title of Mary signifies but
also who Jesus was, and what their own theological forebears, the
Protestant Reformers, had to say regarding this doctrine.

什么苦难都是上帝导致的?
反基的观点是如果上帝存在,那么这个世界必然是没有痛苦的,对吧?
既然现在有痛苦,那么上帝必然不存在,对么?
这个逻辑的前提是:上帝会毫无原则的为人类去除一切痛苦。
基督徒相信在亚当吃禁果前,人类是没有这种生离死别的苦难的。但是自从亚当吃了禁
果,痛苦就来到了这个世界。这是人自己选择了作恶导致的。
基督教的上帝是统治宇宙的,但是基督徒之间对上帝是如何统治的也有分歧。有人认为
上帝是一切事情的直接原因甚至说上帝创造了911。有人认为上帝几乎不闻不问。大多
数基督徒是认为上帝对某些事进行干预,某些事不干预。至于上帝管那些不管那些,只
有上帝自己知道,上帝有自己的计划,我们无法完全了解。
虽然我们无法完全了解上帝,但是我们相信圣经中对人们的启示是真的。

“神的道”
(A) 序言
“道”一词在中国历史和中华文化里, 占有非常重要的地位.[1] 孔子曾说: “
朝闻道, 夕死可矣”(哪怕早上听到道, 晚上就死去也好啊!).[2] 老子在他所著的《道
德经》里也表明“道”的重要: “道为万物之主, 是善人的宝贝, 罪人的中保. 美好的
言词固然可以博取尊荣, 美好的行为固然使人得到尊重, 然而人的不善怎能被剔除弃绝
呢? 所以, 就(算)是立为天子(皇帝), 封为三公(太师、太傅、太保), 财宝无数, 荣华
加身, 还不如坐进这个‘大道’里呢! 古时候为什么重视道呢? 不就是因为在他里面,
寻求就能得着, 有罪就能得赦免吗? 所以道是天下最尊贵的啊!”[3] 现在, 让我们细
心思考这天下最尊贵的道 ¾ “神的道”!

约1:1说: “太初有道, 道与神同在, 道就是神.” 这“道”就是“神的道”(

意思很简单:我这儿是讲道理的地方,你丫要是妄想像中国人那样胡搅蛮缠,哪
凉快哪呆着去!当然你非要把这块牌子理解成“华人与狗不得入内”,我也找不
出反驳的理由,因为普遍地说中国人至今还没认同讲道理是构成文明的一个根本
要素。柏老师这种对基本数学和逻辑知识的尊重的传统至今还保留在西方教育系
统中。
二十多年前,我刚到美国读书时,有一个流行的迷思(myth),就是认为中
国人的数学要好过美国人,中国的数学教育要好过美国的数学教育。到了美国后
才发现远不是那么回事,在文学院里数学最好的学生是美国人,在工学院里数学
最好的学生是美国人,在数学系里最好的学生也还是美国人,而不是中国留学生。
当然,偶尔也有例外,比如,若把北大清华毕业的学生放到美国连体育运动员都

我也觉得LAX不会那么说von Neumann, 应当是夸张的幽默,中文翻译没有忠实原话。
哪有文章指出jennings paper 有问题? 我仔细看了,没全懂,比如他说rational
number 集合Q={eta,1}, with eta rational, Q 的linear span是discrete 的,我觉
得不能理解。 不过这只是文章里很细枝末节的地方。
文章只有15页,居然要看15天。

来自主题: Nursing版 - 求助, Exit Hesi

PROGRAM里面没毕业,但从还没听说过。所有人都参加吗?
据我所知,不同的Nursing学校有不同类型的毕业考试,有的学校用HESI,有的学校用
ATI,或者还有别的?就ATI而言,从Nursing 1就开始有了。如果你能把课本及ATI书结
合起来用、并多做些相关的NCLEX练习,通过毕业考试应该没问题,只是在做配套的ATI
练习时一定要把每一个选项的Rational弄清楚。这些Rational还包含了一些答题技巧,
对学习很有帮助。另外,通过做这些题,你会发现一些重要的实验数据经常反复地拿出
来考。

6月毕业,身心疲惫,彻底放松了一个月;
7月中旬开始预热,白天边带娃边泛泛翻看KAPLAN的书;
8月知道一个同学FAIL 掉,开始紧张。开始做Kaplan Qbank; 还是白天带娃,晚上9点
到12点做题。书是白天带孩子出去玩时看,能看多少算多少,没有特定计划:(
8月中旬开始真正进入复习状态,离考试还有3周。写下详细计划,并把QBANK 的题的
RATIONAL 部分自己认为还需要再加深理解或记忆的部分做了笔记。
9月初考试。前面5-10道觉得不难,很有把握,之后出现多项选择题,难熬的时间是20
到45题,多项选择题太多啦,超过20道,都集中在这部分,45题申请了休息,因为一道
可以心算的药物计算题,居然算了4分钟:( 喝水去卫生间回来,觉得题目开始变得容
易,主要是单选题终于依次出现啦。。。心情从焦躁到平稳。。。但也在碎碎念,上帝
啊,您老人家一定要在75题蓝屏啊,再多做就崩溃了啊。。。
还好,75之后,蓝啦!说不清有多大把握,只是觉得不再遭罪就好,呵呵。。。
感谢板上所有曾支持鼓励的好朋友。人在脆弱的时候,一句贴心的话语都是多么重要:)
复习,只用了KAPLAN 的书 和KA... 阅读全帖

Honestly, even if your paper got published, I didn't see any logical or
rational implication that his books got trashed.
Your response is purely lunatic and emotional. You are talking about *
rational* structure here right? Where is your rationale in your response?
