Spacetown’s Experiment
The Caves of SteelThe Spacer initiative evolves from technological integration to a subtler strategy of withdrawing and encouraging Earthmen to choose expansion themselves.

A City-Side Laboratory

A City-Side Laboratory
A foreign foothold
Spacetown is established as an attempt to modernize Earth and introduce a human-and-robot social model. The project assumes that Earthmen will eventually welcome the Outer Worlds’ methods.
Resistance grows
Early riots and continuing opposition show that technical benefits cannot overcome cultural distrust. The project’s presence becomes a symbol of outside pressure.
The experiment begins with confidence and accumulates political resistance.
Sarton’s New Method

Sarton’s New Method
Understanding before reform
Roj Nemennuh Sarton argues that Spacers must understand Earthmen rather than dismiss them as conservative. Human Spacers cannot bear the City, so he designs a humanoid robot to enter it in their place.
Observation becomes relationship
Daneel is intended to live among Earthmen and record their psychology. Sarton’s method is not merely a new machine; it is an attempt to approach a society through participation.
The experiment makes its creator vulnerable to political opposition.
Baley as a Test Subject

Baley as a Test Subject
A practical candidate
Fastolfe explains that the Spacers have assessed Baley as a potentially useful advocate for colonization. Daneel has conducted Cerebroanalysis and his reactions interest the project’s leaders.
Influence concealed
Fastolfe admits that Baley received a drug intended to make him more receptive to the colonization argument. The disclosure complicates Baley’s emerging agreement by revealing that persuasion was experimentally assisted.
The project studies not only society but the investigator himself.
The Experiment’s Result

The Experiment’s Result
A disappointing response
Baley accepts colonization as plausible but never becomes a fanatic. Fastolfe’s drug cannot make him abandon his practical judgment or accept ideas wholly outside his own thinking.
A useful discovery
Daneel says Baley’s conversation changes Clousarr’s Cerebroanalytic response. The experiment suggests that Medievalist romanticism might be redirected through argument rather than force.
The intended test produces an unexpected social insight.
Withdrawal and Continuation

Withdrawal and Continuation
The official project ends
Spacetown chooses to leave Earth and stop the Sarton investigation. Its leaders believe continued pressure would make the desired cultural change less likely.
The idea remains
Daneel may stay, and Baley may help establish training schools for emigrants. The project’s methods shift from a foreign program to a possible partnership with sympathetic Earthmen.
Withdrawal closes one experiment while opening another.
