When local hypergene life prosperous, deposition relative many; Otherwise when the life is in the murky time, relative small; When deposits the many stratum participation internal heat circulation, the surface activity is relatively violent, has the possibility to mean surface Earth life a disaster time, when deposits the few stratum participation internal heat circulation, the surface activity is relatively stable, has the possibility to mean the life an epacme, this is the Earth life periodicity deconstruction and the newborn basic internal reason is at.

当地表生命繁盛时，沉积就相对较多；反之当生命处于低迷时期时，就相对较小；当沉积较多的地层参与内热循环时，地表活动相对猛烈，就有可能意味着地表地球生命的一个灾难期，当沉积较少的地层参与内热循环时，地表活动相对稳定，就有可能意味着生命的一个繁盛期，这就是地球生命周期性毁灭与新生的根本内部原因所在。

I have been in all my Circumstances a Memento to those who are touch'd with the general Plague of Mankind, whence, for ought I know, one half of their Miseries flow; I mean, that of not being satisfy'd with the Station wherein God and Nature has plac'd them; for not to look back upon my primitive Condition, and the excellent Advice of my Father, the Opposition to which, was, as I may call it, my ORIGINAL SIN; my subsequent Mistakes of the same kind had been the Means of my coming into this miserable Condition; for had that Providence, which so happily had seated me at the Brasils, as a Planter, bless'd me with confin'd Desires, and I could have been contented to have gone on gradually, I might have been by this Time; I mean, in the Time of my being in this Island, one of the most considerable Planters in the Brasils, nay, I am perswaded, that by the Improvements I had made, in that little Time I liv'd there, and the Encrease I should probably have made, if I had stay'd, I might have been worth an hundred thousand Moydors; and what Business had I to leave a settled Fortune, a well stock'd Plantation, improving and encreasing, to turn Supra-Cargo to Guinea, to fetch Negroes; when Patience and Time would have so encreas'd our Stock at Home, that we could have bought them at our own Door, from those whose Business it was to fetch them; and though it had cost us something more, yet the Difference of that Price was by no Means worth saving, at so great a Hazard.

一般人往往有一种通病，那就是不知足，老是不满于上帝和大自然对他们的安排。现在我认识到，他们的种种苦难，至少有一半是由于不知足这种毛病造成的。患有这种病的人大可以从我的一生经历中得到教训。就拿我自己来说吧，正是由于我不满自己原来的境况，又不听父亲的忠告--我认为，我有悖教训，实为我的&原罪&，再加上我后来又犯了同样的错误，才使自己落到今天这样悲惨的地步。当时，造物主已安排我在巴西做了种植园主。如果我自己不痴心妄想发财，而是满足于逐渐致富，这时候我也许已成了巴西数一数二的种植园主了，而现在我却白白地在这荒岛上流落了这么多年，过着悲惨孤寂的生活。而且，我在巴西经营时间不长；就是在这段短短的时间里，我也获利不少。因此我确信，要是我继续经营下去的话，到现在一定拥有十几万葡萄牙金币的家财了。当时，我的种植园已走上了轨道，并且日益兴旺。可是，我偏偏把这一切丢弃，甘愿去当一名船上的管货员，只是为了到几内亚去贩卖黑奴。现在想来，我为什么要这样做呢？要是我守住家业，只要有耐心，经过一段时间之后，同样可以积聚大笔财富，我不是也可以在自己的家门口，从那些黑奴贩子手里买到黑奴吗？虽说价钱贵一点，但这点差价绝不值得自己去冒这样大的风险！
