How all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings.

William Cobus – Aug 21, 2016:

There anyone who loves or pursues or desires to obtain pain itself, because it is pain sed, because occasionally circumstances occur some great pleasure.
