Carl Jung died in 1961. His works won't be out of copyright in most of the world until 2032, in Canada and some other parts of the world until 2012, and in the US it's more complicated. Anything he published in the US before 1923 is public domain in the US. Anything else may or may not be copyright until 2019 depending on whether the copyright was renewed.
Copyright lengths are horribly complicated in the US, and far too long everywhere.
