Welcome to listen!
Under the captions of the Philosophic Building Blocks below there are two choices.
Click on P and you listen to a Presentation of a Philosophic Building Block you have chosen (step 1).
Click on B. This is a short cut to the Building Block you want to study (step 2).
On the computer and tablet you click on the return symbol to get back to where you started.
On the mobile you tap the screen in-between each text you listen to, and the return symbol is still there when you have listened to the whole presentation.
