克尔凯郭尔与卢卡奇马克思主义哲学观的流变

克尔凯郭尔并非卢卡奇偶然提及的学术注脚,而是其理解马克思的背景支援。卢卡奇在不同时期都对克尔凯郭尔作了选择性评述,并将其接受或重构马克思主义哲学的曲折心路历程逐一呈现:通过质疑克尔凯郭尔在人与世界相统一问题上遭遇的“审美—伦理”悖论,青年卢卡奇从心灵掘进到阶级意识,将“主体—总体”辩证图式看作马克思的认识论地平,由此创作出《历史与阶级意识》;之后,为回应该书引起的争议,盛年的卢卡奇以批判克尔凯郭尔的非理性主义为契机,尝试清除“主体—总体”辩证图式中残余的主体形而上学痕迹,开始在方法论维度正视生产实践与经济规律间的有机联系;及至晚年,当卢卡奇立足社会存在,抨击克尔凯郭尔有关主体优先性的宗教幻象时,他又把社会性的“自在—自为”运动内嵌于人性的“主体—总体”辩证图式,并根据超然的悟性,默认马克思主义哲学是将经济规律置于从属地位的劳动本体论,再度退回《历史与阶级意识》的主体形而上学谋划。不难看出,在卢卡奇臧否克尔凯郭尔与马克思的“主体—总体”辩证桥段中,当事人对“人之实然性和应然性的现实统一”问题所秉持的龃龉心态暴露无遗。这也恰好说明,卢卡奇一生都徘徊于正统的马克思主义与人道的马克思主义之间。

Fecundity in some insects is affected by mating status. The effect of mating status on the fecundity and total egg production of Teleogryllus emma （Ohmachi et Matsumura）（Orthoptera： Gryllidae） was examined in this study. The results showed that the pre-oviposition period was shorter for amphigonic females than that for virgin females. However, no significant difference in pre-oviposition was found between amphigonic females and those that had mated with a male with either the phallodeum or testes extirpated. There is no difference in adult longevity between the above four groups. The fecundity and total egg production were much higher in amphigonic females than in those controlled under the three non-amphigonic treatments. The females of T. emma that mated with the testes-extirpated males produced more eggs （up to two-fold more） than both the virgin females and those that mated with the phallodeum-extirpated males, but there was no difference between them. The fecundity-enhancing substances transferred from male to female can stimulate the female to produce more eggs, but this stimulation has to occur in collaboration with sperm.

The SnCl2 reduction of 2-nitrocyclododecanone or 2-bromo-12-nitrocyclododecanone gave a colorless compound 2,3,5,6-bis（ortho-1,10-decylidene）dihydropyrazine 1a characterized by IR, NMR and X-ray diffraction analysis. Crystal data for 1a： Mr = 358.60, monoclinic, space group P2 1/n, α = 0.48028（3）, b = 2.8646（4）, c = 0.77097（6） nm, β = 98.432（12）°, V = 1.04924（19） nm^3, Dc = 1.135 g/cm^3, Z = 2, F（000） = 400 and μ（MoKa） = 0.065 mm^-1. All ^1H- and ^13C-NMR resonance lines of 1a were assigned by DEPT, COSY, HMQC and HMBC technology. In the crystal, the dihydropyrazine ring has a planar structure, two twelve-membered tings adopt [lene2333] conformation, their double bonds have cis-configuration, and the whole molecule has a center of symmetry. In solution, the symmetric ^1H- and ^13C-NMR signals suggest that two twelve-membered rings of 1a may adopt enantiomorphous [ lene2333] conformation existing in a dynamic equilibrium.
