If as Gertrude Stein humorously observed 'there are no straight lines in nature', then Ruehle's art just as readily re-asserts that his paintings and black lines are not to be of nature but transpositions of a deliberately imagined and constructed world. As if to restate matters for the painter Ruehle, there is simultaneously clarity and ambiguous uncertainty that pervades and quite deliberately unnerves the immediate viewing experience of this artist's paintings. It is this very ambiguity and questioning dissonance that makes Torsten Ruehle's paintings so interesting
