var tmp = '# 生活在结构1上\n\n现代学科1以人名1的“名句1”为嚆矢。滥觞于学科2与学科3的期望正失去它们的借鉴意义。但面对看似无垠的未来天空，我想循人名2“名句2”好过过早地振翮。\n\n我们怀揣热忱的灵魂天然被赋予对超越性的追求，不屑于古旧坐标的约束，钟情于在别处的芬芳。但当这种期望流于对思想1主义不假思索的批判，乃至走向思想2与思想3主义时，便值得警惕了。与秩序的落差、错位向来不能为越矩的行为张本。而纵然我们已有翔实的蓝图，仍不能自持已在浪潮之巅立下了自己的沉锚。\n\n“名句3”人名3之言可谓切中了肯綮。人的性质1性是不可祓除的，而我们欲上青云也无时无刻不在因风借力。学科3与学科2暂且被我们把握为一个薄脊的符号客体，一定程度上是因为我们尚缺乏体验与阅历去支撑自己的认知。而这种偏见的傲慢更远在知性的傲慢之上。\n\n在孜孜矻矻以求学科1意义的道路上，对自己的期望本就是在与学科3与学科2对接中塑型的动态过程。而我们的底料便是对不同概念1、不同概念2的觉感与体认。人名4为人名5送去概念3，又维系概念4。他的学科1观念是厚实的，也是实践的。倘若我们在对过往借人名6之言“祓魅”后，又对不断膨胀的自我进行“赋魅”，那么在丢失外界预期的同时，未尝也不是丢了自我。\n\n毫无疑问，从学科2与学科3角度一觇的自我有偏狭过时的成分。但我们所应摒弃的不是对此的批判，而是其批判的廉价，其对批判投诚中的反智倾向。在人名7的观念中，如果在成为狮子与孩子之前，略去了像骆驼一样背负前人遗产的过程，那其“永远重复”洵不能成立。\n\n蓝图上的落差终归只是理念上的区分，在实践场域的分野也未必明晰。譬如当我们追寻概念5时，在途中涉足概念6，这究竟是伴随着期望的泯灭还是期望的达成？在我们塑造学科1的同时，学科1也在浇铸我们。既不可否认原生的性质2性与性质3性，又承认自己的图景有轻狂的失真，不妨让体验走在言语之前。用不被禁锢的头脑去体味人名8的大海与风帆，并效人名9，对无法言说之事保持沉默。\n\n用在结构1上的生活方式体现个体的超越性，保持婞直却又不拘泥于所谓“遗世独立”的单向度形象。这便是人名6为我们提供的理想期望范式。生活在结构1上——始终热爱大地——升上天空。';
