Such liberal thought as survived the success of the Revolution carried on the spirit of Locke's philosophy most truly in respect to religious toleration…With some lip-service to Locke, Whiggism in the eighteenth century represented quite subsidiary elements of his Treatise: that the powers of government remain indefeasibly in the organs where they have once been placed…and that government is at bottom a balance of the vested interests of the realm: crown, landed aristocracy, and corporations…The monopoly of power by the landowning class was contrary not only to Locke's theory of individual rights but also to his theory of the importance of property in general 496-497

当然，理论与现实的距离永远存在。洛克思想的复杂性也决定了其影响的复杂性。比如在英国，18世纪的辉格党虽口头上标榜洛克的学说，但实际上却采用了他的一些次要思想，如关于政府权力一旦确定，就不可取消地永远由该机构所拥有的思想；而权力的平衡归根到底却成了王国既得利益势力、王室、土地贵族和公司的权力平衡，其中土地所有者阶级垄断权力的状况也违反了洛克关于一般个人权利，特别是关于财产权利的学说（《思想史》，192-193；《自由主义》，180）。

These compounds are of substantial interest both inviewpoints of theory and practical applications, mainlyunder the stimulus to achieve synthetic models either foractive sites of iron-sulfur proteins or for transitionmetal catalysts. This thesis describes the synthesis, structures andconformations of 51 new iron-sulfur cluster complexes,which have been characterized by elemental analysis andstandard spectroscopic methods. In addition, single-crystalX-ray diffraction analyses were performed for 4 representa-tive new compounds. Reactivities of μ-〓 with mono- and di- Grig-nard reagents derived intermediates toward various organicelectrophilic substrates were studied, along with complexa-tion of arynyl-containing iron-sulfur clusters by 〓Thus, several bridged, non-bridged, monomeric, dimeric,homonuclear, heteronuclear iron-sullfur and iron-sulfur co-balt-carbon cluster complexes were synthesized. A novelreaction and convenient route for the synthesis in highyield of tetranuclear iron complexes 〓 containing atetracoordinated sulfur atom was discovered, whereas aplausible mechanism based on experimental results was propo-sed for the formation of the new cluster type.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
