		| Abstract: | 
		Though the title points to a wider program than can be accommodated in one individual paper, the meeting was called with such considerations as a background. This paper then raises primarily questions that people might ask in connection with Zdeněk Kopal and his work, rather than giving comprehensive answers. A few general thinking points are presented first, followed by a selection of particular illustrations arranged by the several decades over which Kopal was active in astronomical science. A concluding section returns to some general and personal reflections. |
