6Although common prejudice still believes that the sole essential basis of our knowledge is given exclusively from outside and that "nihil est in intellectu quod non antea fuerit in sensu, it nevertheless remains true that the thoroughly respectable atomic theory of Leucippus and Democritus was not based 0 any observations of atomic fission but on a "mythological" conception of smallest particles, which, as the smallest animate parts, the soul-atoms, are known even to the still palaeolithi inhabitants of central Australia.9 How much "soul is projected into the unknown in the world of external appearance is, of course, familiar to anyone acquainted with the natural science and natural philosophy of the ancients.

虽然普通的偏见依然相信我们知识的唯一的本质的基础是来自外部世界，and that "nihil est in intellectu quod non antea fuerit in sensu，路斯帕和德谟克利特令人敬佩的原子理论并不基于任何对原子裂变的观察，而是基于"神话的"最小粒子的概念，这是作为最小的有生气的部分，灵魂的原子，这些也为中澳大利亚旧石器时代的居民所知。有多少"灵魂投射进世界外观的未知中，当然，也和任何人所熟知的古代人的自然科学、自然哲学相似。

In addition, the changes of molecular geometry, atomic natural charge and IR spectra of the reaction system during the crucial step of O to attack H showed that the rupture of C—H bond and the formation of O—H bond were concerted stepwise. Obvious changes of atomic natural charge happened to atoms C(1), H(11), O(28), O(29) and N(27). The bond lengths and bond angles related to these atoms were also varied greatly.
