| − | One of the earliest thinkers of the modern age to postulate the potentials of artificial life, separate from [[artificial intelligence]], was math and computer prodigy [[John von Neumann]]. At the [[Hixon Symposium]], hosted by [[Linus Pauling]] in [[Pasadena, California]] in the late 1940s, von Neumann delivered a lecture titled "The General and Logical Theory of Automata." He defined an "automaton" as any machine whose behavior proceeded logically from step to step by combining information from the environment and its own programming, and said that natural organisms would in the end be found to follow similar simple rules. He also spoke about the idea of [[self-replicating machine]]s. He postulated a machine – a [[kinematic automaton]] – made up of a control computer, a construction arm, and a long series of instructions, floating in a lake of parts. By following the instructions that were part of its own body, it could create an identical machine. He followed this idea by creating (with [[Stanislaw Ulam]]) a purely logic-based automaton, not requiring a physical body but based on the changing states of the cells in an infinite grid – the first [[cellular automaton]]. It was extraordinarily complicated compared to later CAs, having hundreds of thousands of cells which could each exist in one of twenty-nine states, but von Neumann felt he needed the complexity in order for it to function not just as a self-replicating "machine", but also as a [[universal computer]] as defined by [[Alan Turing]]. This "[[Von Neumann universal constructor|universal constructor]]" read from a tape of instructions and wrote out a series of cells that could then be made active to leave a fully functional copy of the original machine and its tape. Von Neumann worked on his [[automata theory]] intensively right up to his death, and considered it his most important work.

| | 现代最早提出人工生命（独立于人工智能）潜力假说的思想家之一，是数学和计算机天才[[约翰·冯·诺依曼]](John von Neumann)。20世纪40年代末，[[莱纳斯·鲍林]]（Linus Pauling）在加利福尼亚州帕萨迪纳市举办了希克森研讨会，冯·诺依曼在会上发表了题为“自动机的一般逻辑理论”的演讲。他将“[[自动机]]”定义为：通过结合环境信息和自身编程，可逻辑化地逐步执行行为动作的任何机器，并表示，最终人们会发现自然生物也遵循着类似的简单规则。他还谈到了自我复制机器的想法。他设想了一台机器——一台自动运动的机器——由一台控制计算机、一个构造臂和一长串指令组成，漂浮在零部件的湖中。通过执行它自己身体的一部分的指令，它就能制造出一台完全相同的机器。他遵循这个想法，创建了一个纯粹基于逻辑的自动机(与[[Stanislaw Ulam]]一起)，不需要物理实体，而是基于无限网格中细胞状态的变化——这是第一个[[细胞自动机]]（[[元胞自动机]]、[[格状自动机]]）。与后来的CAs相比，它是非常复杂的，它有成千上万的细胞，每个细胞可以存在于29个状态中的一个，但是冯·诺依曼觉得他需要这种复杂性，以便它不仅能作为一个自我复制的“机器”运行，而且能像[[艾伦·图灵]]定义的那样成为一台通用计算机。这个“通用构造函数”读取指令磁带，并写出一系列单元格，这些单元格可以被激活，从而留下原始机器及其磁带的功能齐全的副本。冯·诺依曼一直致力于他的自动机理论，直到他去世，并认为这是他最重要的工作。 | | 现代最早提出人工生命（独立于人工智能）潜力假说的思想家之一，是数学和计算机天才[[约翰·冯·诺依曼]](John von Neumann)。20世纪40年代末，[[莱纳斯·鲍林]]（Linus Pauling）在加利福尼亚州帕萨迪纳市举办了希克森研讨会，冯·诺依曼在会上发表了题为“自动机的一般逻辑理论”的演讲。他将“[[自动机]]”定义为：通过结合环境信息和自身编程，可逻辑化地逐步执行行为动作的任何机器，并表示，最终人们会发现自然生物也遵循着类似的简单规则。他还谈到了自我复制机器的想法。他设想了一台机器——一台自动运动的机器——由一台控制计算机、一个构造臂和一长串指令组成，漂浮在零部件的湖中。通过执行它自己身体的一部分的指令，它就能制造出一台完全相同的机器。他遵循这个想法，创建了一个纯粹基于逻辑的自动机(与[[Stanislaw Ulam]]一起)，不需要物理实体，而是基于无限网格中细胞状态的变化——这是第一个[[细胞自动机]]（[[元胞自动机]]、[[格状自动机]]）。与后来的CAs相比，它是非常复杂的，它有成千上万的细胞，每个细胞可以存在于29个状态中的一个，但是冯·诺依曼觉得他需要这种复杂性，以便它不仅能作为一个自我复制的“机器”运行，而且能像[[艾伦·图灵]]定义的那样成为一台通用计算机。这个“通用构造函数”读取指令磁带，并写出一系列单元格，这些单元格可以被激活，从而留下原始机器及其磁带的功能齐全的副本。冯·诺依曼一直致力于他的自动机理论，直到他去世，并认为这是他最重要的工作。 |

| − | Philosophy scholar [[Arthur Burks]], who had worked with von Neumann (and indeed, organized his papers after Neumann's death), headed the Logic of Computers Group at the [[University of Michigan]]. He brought the overlooked views of 19th century American thinker [[Charles Sanders Peirce]] into the modern age. Peirce was a strong believer that all of nature's workings were based on logic (though not always deductive logic). The Michigan group was one of the few groups still interested in alife and CAs in the early 1970s; one of its students, [[Tommaso Toffoli]] argued in his PhD thesis that the field was important because its results explain the simple rules that underlay complex effects in nature. Toffoli later provided a key proof that CAs were [[Reversible computing|reversible]], just as the true universe is considered to be.

| − | [[Christopher Langton]] was an unconventional researcher, with an undistinguished academic career that led him to a job programming [[Digital Equipment Corporation|DEC]] mainframes for a hospital. He became enthralled by Conway's Game of Life, and began pursuing the idea that the computer could emulate living creatures. After years of study (and a near-fatal hang-gliding accident), he began attempting to actualize Von Neumann's CA and the work of [[Edgar F. Codd]], who had simplified Von Neumann's original twenty-nine state monster to one with only eight states. He succeeded in creating the first self-replicating computer organism in October 1979, using only an [[Apple II]] desktop computer. He entered Burks' graduate program at the Logic of Computers Group in 1982, at the age of 33, and helped to found a new discipline.
