Excerpt from book: changes; and even if the cause of the variation is of a psychological nature, we can hardly call it an effort, unless we give a very unusual extension to the meaning of the word. The truth is, it is necessary to dig beneath the effort Innk for a dpppfr cruise. This is especially necessary, we believe, if we wish to get at a cause of regular hereditary variations. We are not going to enter here into the controversies over the transmissibility of acquired characters; still less do we wish to take too definite a side on this question, which is not within our province. But we cannot remain completely indifferent to it. Nowhere is it clearer that philosophers can not to-day content themselves with vague generalities, but must follow the scientists in experimental detail and discuss the results with them. If Spencer had begun by putting to himself the question of the heredita- bility of acquired characters, his evolutionism would no doubt have taken an altogether different form. If (as seems probable to us) a habit contracted by the individual were transmitted to its descendants only in very exceptional cases, all the Spencerian psychology would need re-making, and a large part of Spencer's philosophy would fall to pieces. Let us say, then, how the problem seems to us to present itself, and in what direction an attempt might be made to solve it. After having been affirmed as a dogma, the transmissibility of acquired characters has been no less dogmatically denied, for reasons drawn o priori from the supposed nature of germinal cells. It is well known how Weismann was led, by his hypothesis of the continuity of the germ-plasm, to regard the germinal cells ? ova and spermatozoa ? as almost independent of the somatic cells. Starting from this, it has been claimed, and is still claime...

读后感
看《时间之箭》，里面好像说过这样的观点，时间的单向流动性，是因为我们的大脑的工作方式所产生的感受——我们的大脑的思考与记忆的机制，也正好像算盘一样，通过算珠从有序到无序演化，来储存记忆运行思考，我们思考的方向，赋予一切外在事物的演化方向：从有序到无序，所以...
评分 评分生命的本质在于是传送生命的运动，即生命之流。生物是生命的载体，个体是负载了材料的生命之流。 生命的特征之一是可以分化出不同的进化路线，所有进化路线都没有终点。 生命是一种内在冲动，生命的过程是进化。生命的状态是变化。我们自身是我们自出生起至今的历史。通过变化...
评分如果你是一位《星际迷航》迷，在连续追看了它现有的11部系列电影之后，一定会对剧中关键性人物Spock有非常深刻的印象。作为人类和瓦岗人的混血后裔，Spock一直在思考这样一个问题：选择做瓦岗人还是人类，选择理智还是感性？这个问题在《星际迷航6》中，给出了确切答案：Logic ...
评分生命就是从这个决定论的机械世界中越狱成功的那世界本身的不安分的一面，所谓的“原始冲动”就是代表着从确定到不确定的，从有序到无序，从必然到自由的那种能量传递的倾向。 经历几十亿年的发展，生命得以产生并且以智慧的形态达到巅峰，漫长的过程，宣告生命不是目的论的产...
