relatively large brain. It seems, with por- REFERENCES 

 poises, that everyone sooner or later becomes 

 interested in the intelligence of these likable 1 

 little animals . This must surely lead to gener- 

 alized thoughts on the meaning of intelligence 

 itself. 2 



Now, it so happens also that a great number 

 of people are fascinated in what is called "outer 3 

 space." It is highly probable that this also 

 will influence our train of thoughts. I suggest, 

 therefore, that someone is likely to propose 

 next (if he has not already done so) a project 

 for submitting to the judgment of porpoises 

 samples of signals picked up from outer space 

 (probably transmitted by other beings) . Perhaps 

 this clever animal will recognize "meanings" 

 before we humans do. Why not? Why should other 

 beings be more like humans than like porpoises? 

 What happens next (if any action at all is taken) 

 is a search for an instrument to communicate with 

 porpoises and thus talk quite fluently in all 

 the languages the porpoise understands . 



We have now "come round full circle" because 

 obviously the investigation depends for success 

 upon new types of instrumentation; special 

 transducers, linkages and analyzers. Just what 

 is to be the nature of these new instruments? 

 Who knows for sure that porpoises rely mostly on 

 sound for their information? Perhaps they are 

 still more perceptive through some other sense. 

 Maybe they can better taste than hear certain 

 details of important information, like the loca- 

 tion of a distant school of fish, for example. 

 Successful answer of this critical question 

 hinges first of all on the interest of someone 

 in understanding taste phenomena. It depends 

 also upon someone who can somehow put together 

 instrumental means for making the actual measure- 

 ments that are required or, alternatively, some- 

 one who is capable of patiently finding out what 

 things are available and how best they can be put 

 together for this particular purpose. 



This train of hypothetical events might be 

 allowed to go "on and on" but I will stop it 12. 

 here to ask the grand final question. Where 

 was the "instrument man" during this "trolley 

 ride?" Did he get off at each place when a new 

 type of transducer was required or did he ride 

 along and learn as he went? Did he get to liking 

 porpoises?

My personal feelings are, and history seems 

 to confirm, that the instrument man indeed went 

 along all the way. He was curious and interested 

 from beginning to end--and he got to liking 

 porpoises very much. I find myself somewhat 

 impatient when I hear him spoken of as a "spe- 

 cialist." I don't yet know just how to define 

 him, really, but certainly he isn't simply that.'
