Transhumanism aims to bring about radical human enhancement. In ‘Truly Human Enhancement’ Agar (2014) provides a strong argument against producing radically enhancing effects in agents. This leaves the transhumanist in a quandary—how to achieve radical enhancement whilst avoiding the problem of radically enhancing effects? This paper aims to show that transhumanism can overcome the worries of radically enhancing effects by instead pursuing radical human enhancement via incremental moderate human enhancements (Weak Transhumanism). In this sense, weak transhumanism is much like traditional transhumanism in its aims, but starkly different in its execution. This version of transhumanism is weaker given the limitations brought about by having to avoid radically enhancing effects. I consider numerous objections to weak transhumanism and conclude that the account survives each one. This paper’s proposal of ‘weak transhumanism’ has the upshot of providing a way out of the ‘problem of radically enhancing effects’ for the transhumanist, but this comes at a cost—the restrictive process involved in applying multiple moderate enhancements in order to achieve radical enhancement will most likely be dissatisfying for the transhumanist, however, it is, I contend, the best option available.

超人类主义旨在实现彻底的人类进步。在“真正的人类增强”中，琼脂 (2014) 提供了反对在代理中产生根本增强效果的有力论据。这让超人类主义者进退两难——如何在实现激进增强的同时避免激进增强效果的问题？本文旨在表明超人类主义可以通过渐进适度的人类增强（弱超人类主义）而不是追求激进的人类增强来克服从根本上增强效果的担忧。从这个意义上说，弱超人类主义在目标上很像传统的超人类主义，但在执行上却截然不同。鉴于必须避免从根本上增强效果所带来的局限性，这种超人类主义的版本较弱。我考虑了无数对弱超人类主义的反对意见，并得出结论，该帐户每一个都存在。本文提出的“弱超人类主义”的结果是为超人类主义者提供了解决“激进增强效果问题”的方法，但这是有代价的——为了实现激进的应用多个适度增强所涉及的限制性过程增强很可能会让超人类主义者不满意，但是，我认为，这是可用的最佳选择。
