The author discusses some difficulties which it might be encountered in contacting extraterrestrial civilizations. In the course of the discussion, he reviews certain statements advanced by various persons. He states that it is necessary to seek civilizations, to detect them, to come into contact with them through radio-signals etc. In such a restricted astronomical aspect, the difficulties are mainly technical. However it is necessary to continue questing, for cosmic signalling in the hope that man will encounter an intelligence so similar to him that he will recognize its signs.
