Semeiotic Wheel
How does Goethe´s theory of colors relate to Peirce´s theory of categories? Did you know that it possible to find out the 66 classes of signs by applying a special logic of colours in the process of determination among the three sign correlates? Here you will find out which classes of signs are allowed while you rotate the wheel to explore its possibilities. Find out how our Periodic Table of Classes of Signs can be arranged in the triangular shape following this logic of colors. You will understand why qualisings are red and legisigns are blue.

Periodic Table of Classes of Signs
The 66 classes of signs arranged in this triangular shape show regular periods revealing the increase of complexity of semeiosis as it reaches communication, as well as phases that describe the whole process of inquiry. Here you will get an analysis and useful examples of each class of sign, as well as the opportunity to post you own thoughts and examples about them. Each class is also represented in a figure – the Solenoid of Semeiosis – showing how the sign aspects relate to one another.
