Biologists view life as transient while theologians see it as eternal. An unbiased definition for life would respect both views until one or both were eliminated by evidence. This paper identifies pre-requisites for such a definition. First among these is that all assumptions be made explicit. Currently "life" is surrounded by implicit assumptions, e.g., that it is what organisms lose at death or that it is eternal, that its quality is inversely related to personal distress, that it originated some four billion years ago, and that animate matter can be distinguished from inanimate matter. None of these assumptions are supported by data. It is possible therefore that "life" is as meaningless as phlogiston. If life has meaning, i.e., if it is true, it must be as permanent as buoyancy, gravity, electricity, and the other truths of nature. Any definition for life that would permit such truth to be seen must be free of unwarranted assumptions. For the moment, at least, such a definition would need to be loosely structured and broadly focused. It would need to describe the long and convoluted process by which matter and energy form organisms which then evolve to form conscious organisms which then explore nature and eventually discover truth. Such a definition would include all the reactions and interactions of matter and energy and all the aspects of conscious discovery. It would suffer from superficiality, but, by being free from bias, provide a foundation for dialogue between biologists and theologians.
生物学家认为生命是短暂的,而神学家则视其为永恒的。一个公正的生命定义会兼顾这两种观点,直到其中一种或两种观点被证据推翻。本文确定了这样一个定义的先决条件。首要条件是所有假设都要明确表述。目前,“生命”被一些隐含假设所包围,例如,它是生物体死亡时失去的东西,或者它是永恒的,其质量与个人痛苦成反比,它起源于大约40亿年前,以及有生命的物质可以与无生命的物质区分开来。这些假设都没有数据支持。因此,“生命”有可能和燃素一样毫无意义。如果生命有意义,也就是说,如果它是真实的,它必须像浮力、重力、电以及其他自然真理一样永恒。任何能让这种真理显现的生命定义都必须摆脱无端假设。至少目前,这样一个定义需要结构宽松、范围广泛。它需要描述物质和能量形成生物体,然后生物体进化形成有意识的生物体,接着有意识的生物体探索自然并最终发现真理的漫长而复杂的过程。这样一个定义将包括物质和能量的所有反应和相互作用以及有意识探索的所有方面。它可能会流于表面,但通过没有偏见,为生物学家和神学家之间的对话提供一个基础。
