"The original form of every vision of the future is the vision, the dream, the connection of non-existent realities. The path from the future to the present is only possible through visual language, through art. It makes people visionary, it allows them to experience and comprehend previously unnoticed processes. In order to trigger this potential even in people who have no special equipment for it, Liedtke's art formula is visibly kept simple: 

 it is oriented towards the evolution of innovations."

"Liedtke is a thinker and researcher whose partly intuitive,  
partly conscious approach to the findings of various disciplines in the humanities and natural sciences is the inspiration for his artistic work and his work as an author. Thus, among other things, he has created and continues to create works of art such as paintings and collages that abstract complex scientific processes or conditions. “  

"Liedtke's creative work is thus reminiscent of artists such as Leonardo da Vinci, who also used their creativity in an interdisciplinary way, dissolving the usual divisions between matter and spirit, scientific knowledge and artistic imagination. And like da Vinci's works, Liedtke's also identify him as a visionary, a person who, in the consequences of his thoughts and actions as an artist of the scientific research is not infrequently years ahead."

"In modern art, the so-called autodidact artists (the painters of the Brücke, Kandinsky, Matisse, etc.) play a special role, since they have never been academically degenerated, i.e. corrupted by conformity, and therefore have not had to follow the so-called rules either. With Liedtke, the autodidact visual artist, we learn through his many books with scientific content that he is also the autodidact scientist who, with a free look and free thinking, explored content that was only explored later by the so-called scientists and thus made it to the Nobel Prize. “
