&amp;lt;b&amp;gt;Peter Janich&amp;lt;/b&amp;gt; (born 1942) is a professor of philosophy at the [http://en.wikipedia.org/wiki/University_of_Marburg University of Marburg]. Janich studied physics, philosophy and psychology at the Universities of Erlangen and Hamburg. He attained a doctorate in philosophy in 1969 and during 1969/70 was a guest lecturer at the University of Texas in Austin. From 1973-80 he was a professor for science theory of the accurate sciences at the University of Konstanz. Since 1980 he has held the chair for systematic philosophy with an emphasis on theoretical philosophy at the [http://en.wikipedia.org/wiki/Philipps_University_of_Marburg Philipps University of Marburg].&lt;br /&gt;
&lt;br /&gt;
Janich is the joint founder and representative of the approach of [http://en.wikipedia.org/wiki/Methodical_culturalism methodical culturalism], a development of the [http://en.wikipedia.org/w/index.php?title=Methodical_constructivism&amp;amp;amp;action=edit&amp;amp;amp;redlink=1 methodical constructivism] of the [http://en.wikipedia.org/w/index.php?title=Erlanger_school&amp;amp;amp;action=edit&amp;amp;amp;redlink=1 Erlanger school] (&amp;quot;Erlanger constructivism&amp;quot;). He developed the concept of [http://en.wikipedia.org/wiki/Protophysics Protophysics] with Paul Lorenzen and R?diger Inhetveen. - &amp;lt;em&amp;gt;Wikipedia&amp;lt;/em&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Paul Lorenzen, noted for his work on constructive foundations of mathematics was a follower of Dingler, at least with respect to the foundations of geometry and physics. The so-called Erlangen School of followers and allies of Lorenzen, including [http://en.wikipedia.org/w/index.php?title=Kuno_Lorenz&amp;amp;amp;action=edit&amp;amp;amp;redlink=1 Kuno Lorenz], [http://en.wikipedia.org/w/index.php?title=Wilhelm_Kamlah&amp;amp;amp;action=edit&amp;amp;amp;redlink=1 Wilhelm Kamlah], and [http://en.wikipedia.org/wiki/Peter_Janich Peter Janich], and more indirectly, [http://en.wikipedia.org/w/index.php?title=Juergen_Mittelstrass&amp;amp;amp;action=edit&amp;amp;amp;redlink=1 Juergen Mittelstrass], is thus in large part pursuing a modernized version of Dingler?s program which claims to incorporate [http://en.wikipedia.org/wiki/Theory_of_relativity relativity], [http://en.wikipedia.org/wiki/Quantum_mechanics quantum theory] and [http://en.wikipedia.org/wiki/Quantum_logic quantum logic]. - &amp;lt;em&amp;gt;Hugo Dingler?s Wikipedia page&amp;lt;/em&amp;gt;&lt;br /&gt;
