I'm looking at the Daisy 953 as my first air rifle. It's cheap and accurate.
It's single-stroke pneumatic, so doesn't have the kick of the spring guns.
I'm thinking about using it for target training at home and small pest

发帖数: 1 | 28 大约五年以前，我过着游手好闲的日子。无事可做，那年秋天，便去外地观摩
一个民间博览会。博览会的名字叫做“在你喜欢的任何地方种树”。这个博览会吸引了
来自全国各界的种树爱好者。顾名思义，这些人不顾舟车疲顿，聚集在一块儿，为的是
展示，分享自己亲手种的树，尤其侧重于交流它们的栽种地点。注意，这种活动和环保
呀，育林呀可一点儿关系也不沾。
我在博览会上见识到了形形色色的种树狂人。有富人专门在印度洋上买了一个
极小的小岛，然后把岛上所有树都砍光，直到大地无限趋于平坦。几块草场，一些石头
也不妨碍小岛一览无遗得就像剥了皮的刺猬。忙活完了，富人又在距离海岸线不远处种
下孤零零一棵树。他带来了大量小岛的航拍照片，和那棵树的几片叶子，经纬坐标图。
岛上所有活下来的猴子都守着那棵树，远看仿佛挂满了摇摇欲坠的红毛丹。
据谣传，博览会的幕后赞助方是一个低调的互联网机构。该机构的头目十分痴
迷于种树。还是据谣传，早在20世纪90年代，此人尚幼，在自家大院的房顶上成功栽下

发帖数: 675 | 34 看到许多人对圣经指指点点，颇有微词，并常用基督教的一些表现来否定圣经。在信主
爱主的人眼中，圣经是完全正确的，庄严的，神圣的。当人的认知和圣经冲突时，我们
该以什么样的标准来衡量对错？其实人定的标准是不长久、不稳定的，（连度量衡的标
准在一段时间后都要调整）只有圣经的话语才是真理，是永恒的标准。
真理的标准
人对神的认识，根据神对人的启示；没有神的启示，人不能认识神，甚至不能认识自己
，更无从认识宇宙的来源去向。真实知识的来源，乃是神的启示。所谓自然神学，或天
然神学，无非是人藉万物或本身的理性，揣摩或猜度神的事物。圣经说，“神的事情，
人所能知道的，原显明在人里面；因为神已经给他们显明了。”(罗一19)此等天然的知
识，只能算是最原始、最起码的知识。宇宙万物，固然显明独一主宰的存在，但这位独
一主宰的本质、属性、经纶、目的、旨意，则非藉祂自身的启示不能及之。
基督教不是一种自然宗教，它本身是根据神的启示而产生的。没有神的启示，就没有基
督教。基督教之存在，基于神说了话。然而，神并不是直接的说话，乃是在基督里，并
藉着基督说话，故此，准确一点说，基督教乃是神在基督里的启示。彼得在马太十... 阅读全帖 |

===================
第二世纪的新柏拉图主义
于第二世纪，新柏拉图主义的先锋阿帕米亚之努曼尼亚斯（Numenius of Apamea）提出
一个新发展，其特色是将造物者降级，这是因为造物者与不驯的物质发生接触，因而必
须和宇宙的第一原则分开来。这第一原则是本身在进行自我思想（self-intellection
）的一个nous，而这自我思想的内容即是理型。甚至这正是所有理型的总合，是「存有
」的本身，这或许可被想成一个心思，而整个的真实都对这心思同时显现。第二原则亦
是nous，但其思想是外指的。当它思想第一原则时，它是「往上」指涉，当它执行其造
物者的功用时，则是「往下」指涉。
第二世纪斐罗的影响
深受柏拉图主义影响的斐罗认为，人类乃是一个直接被神所造之「理性魂（rational
soul）」和神所吹入生命之气的尘土的溷合体。带着「非理性魂（irrational soul）
」的身体并不是神直接创造的，而是由神的能力（powers）所创造，它不过就是魂更高
部分—理性魂—的居所罢了。 斐罗的神学深深的影响了随后的亚历山太学派。这导致

慕迪神学手册
因为圣灵是三位一体的其中一位，所以在神学上，关于圣灵的位格和他的工作是十分重
要的。众所周知，那里有神的真理，那里就有伪真理的传播，混淆和破坏了正统的教义
。圣经中有根多关于圣灵的教训，我们该用特别的一章，探讨这个重大的神学论题。
圣灵的格性
从圣灵的身分（Identity）来确定了他的格性（Personality）
在不少人心目中，人格（personality）只能存在于人。这就好象说，格性只
关乎有限的存在（finite beings），而不关乎无限（infinite）的存在。因为人是按
神的形象而造，我们有理由相信，神和人中间是有相似的特性的。「我们可以从对人性
的研究，建立起一些对神圣格性的了解，因为人是按照神的样式被造的。」格性可以简
单界定为：拥有智慧、感情和意志；故此我们可以说，圣灵是拥有智慧、感情和意志，
这足以证明，他是一位既有位格（person）又有格性的神。圣灵有时也被人视为一件「
物」，称作「它」，或被视为一种影响力。本章要证明，圣灵不单有影响力，而且是有
