Sourced, dated quotes from Carl Sagan

Carl Sagan
said · Oct 1994

— Bringing Science Down to Earth (1994), co-authored with Anne Kalosh, in Hemispheres (October 1994), p. 99; this is similar to statements
Carl Sagan

— "Shadows of Forgotten Ancestors" (1992) (co-written with Ann Druyan)
Carl Sagan

Carl Sagan

Carl Sagan
