在无边无际的星海间，基金会的探测器渐行渐远。
经过了外星太阳与外星海渡，经过了外星棕熊与外星蜂蝴——
但从未有树。

在每一个世界，那些被蓝色充满，那里的植物丰富或只占极少数，
他们拉低飞行器，穿过峡谷、平原和沃土，
但从未有树。

Zeta Nine 的第十三世界充斥着鲜花、灌木，甚至葡萄藤。
草，苔，还有藻，把水染成绿与蓝——
但从未有树。

在克伦布尔开山的峭壁上，岩石柱直指天空。
他们在阳光下喝水，呼气，却缺少树叶使空气流通——
他们不是树。

O5-4 对 O5-3 说，“星星有那么多，这怎么可能呢？
有狮，牛，甚至鹅畜…棉花，亚麻，甚至羊绒物——
但是没有一棵树。”

他们争辩，年复一年地书写，随着数据像久远的眼泪一样流泄，
来自与生命共舞和闪耀的世界，来自和平的世界，来自纷争的世界——
但没有树木。

人类跳出垂死的地球，跳向它诞生的摇篮之外，
长久以来，流离失所都是恒星的宿归——
但不对树木如此。

人类现在统治着大量的行星，近至古老的地球，远至黯淡黑洞。
在每一个人类居住的世界上，人们都从地球上带来了他们所能带来的生命。

但从未有树。
