衰老作为文学史上永不“衰老”的经典主题，经陶渊明、杜甫、白居易等人的沿扬流波，行至宋代时已经变为了一种成熟的书写样式。作为衰老书写之“集大成者”，苏轼和辛弃疾在中年阶段就创作了数量可观的述老词，未老却先频频言老。比较苏、辛在老年想象中所映射的中年心境，不仅能够管窥二人同中有异的文化性格与生命意志，也能为述老作品相关研究增添阶段性语料和个案语料，观照衰老书写背后所凝聚的民族文化心态。

在对衰老的情感态度上，苏轼与辛弃疾产生了强烈的共鸣，二人时时叹老，也曾抗老，亦能安老。他们利用词体长于言情的优势，将对衰老现象的理性思考与感性体验充分结合，在述老词中糅入了深幽复杂的心绪以及对生命和宇宙的深沉叩问。但在二人相似的情感外壳下，却也有着不一样的心境与人生感受。在题材意蕴上，辛弃疾的述老词中常常流露出浓重的悲愤情绪，情感表达所爆发的力度与强度胜于苏轼。而苏轼则常常将衰老书写与故土情结联系在一起，这在辛词中较为少见。在情感走向上，辛弃疾对衰老的态度矛盾且多变，始终未曾与衰老真正和解，但他的意志力与豪气却赋予了其词一种坚韧的硬度与深刻的悲剧意识。而苏词则呈现出越老越不忧老的趋势，思想上的多元与圆融使其能够随性自然地接受老并超脱老之桎梏。

Aging, as a classic theme that never “ages” in literary history, has evolved into a mature writing style in the Song Dynasty after being carried forward by such figures as Tao Yuanming, Du Fu, and Bai Juyi. As the “culmination” of aging writing, Su Shi and Xin Qiji have created a considerable number of Ci poetry expressing aging themes during their middle-aged stage, often speaking of aging before actually aging. By comparing the middle-aged mindsets reflected in Su and Xin's portrayal of old age, we can not only glimpse the similarities and differences in their cultural characters and life wills but also add staged and individual corpuses to relevant research on aging writing, reflecting the national cultural psychology underlying such depictions.

In terms of their emotional attitudes towards aging, Su Shi and Xin Qiji resonate strongly, often lamenting, resisting, and accepting aging. Leveraging the advantage of Ci poetry in expressing emotions, they fully integrate rational thinking and sensuous experiences about aging, incorporating profound and complex moods and profound inquiries into life and the universe into their poetry. However, beneath their similar emotional shells, they possess distinct mindsets and life perceptions. In terms of subject matter and implications, Xin Qiji's poetry often reveals a strong sense of sorrow and indignation, with a greater intensity and force in emotional expression than Su Shi. In contrast, Su Shi often connects aging with his attachment to his hometown, which is relatively rare in Xin's poetry. In terms of emotional direction, Xin Qiji's attitude towards aging is contradictory and changeable, never truly reconciling with it. His strong willpower and heroism, however, endow his poetry with resilience and profound tragic consciousness. Conversely, Su Shi's poetry exhibits a trend of becoming less worried about aging as he ages, with his ideological diversity and harmony enabling him to naturally accept and transcend the shackles of aging.
