Wang-ch'ung(왕충) negated the theory of efficacy between the Heaven and a Man(천인감응) based on Yin Yang(음양) and Five Elements(오행) that was popular at that time. The Heaven is just solid one without a mouth and ears. The order of nature is circling in its own way regardless of the will of human being. Jung classified psychological types of the human being into the introversion and extroversion. From this point of view, Wang-ch'ung(왕충) is belong to extroversion philosophy. He criticized modern society by using effect and evidence, and expressed it as critical moral philosophy and political ideal.

This study evaluates the flow of Taoism in the change of knowledge that accompany the passage of time beyond school-centered studies. In particular, it is to understand the Tao(道) and T'ien(天) of "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" in the thought of T'ien at the time. The thought of T'ien at that time was based on the T'ien in "Mencius". There are two meanings of T'ien in "Mencius", and also of T'ien in "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$". This study examins that idea that the T'ien in "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" were influenced by the thought of T'ien in "Mencius". It also reveals the T'ien theory of Wang Ch'ung(王充) which is influenced by Taoism. Also, in the course of examining the relation of T'ien theory of Wang Ch'ung with T'ien theories of "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$", it is more embodied that T'ien theories of "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" were affected by the previous T'ien theories. Furthermore, the meanings of Tao in "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" are revealed.

Semiempirical MO calculations using the PM3 method are performed on the reactions of acetate esters with substituted phenolate anions. The mechanistic change from rate-limiting formation to breakdown of the anionic intermediate is shown to occur in the gas-phase, especially for meta-nitrophenyl acetate. However the mechanistic change-over takes place at a lower basicity ($pK_0$) of the anion nucleophile than found for the corresponding formate. This lowering of $pK_0$ has been ascribed to the electron donating effect of the methyl group in the acetate. For the reactions involving rate-limiting breakdown of the intermediate, the large Bronsted coefficients, ${\beta}_X({\beta}_{nuc})$, are expected in general, but the magnitude increases to a larger value and the pK0 is lowered accordingly, when an electron-donating nonleaving group, like $CH_3$, is present. This type of nonleaving group effect provides a necessary condition for the carbonyl addition-elimination mechanism with rate-limiting breakdown of the intermediate.
