I think I better add in here that if a person interprets the Epicurean principles to be "tranquility is the goal" (as it appears that the above blogger J. Crago does) then it will appear that there are more differences between the ethical Epicurean and Cyrenaic teachings. There are however more differences between the epistemology of each one, than the ethical. I think it would be right to say that Cyrenaic leans toward skeptical and Epicureanism is empirical.
Here on this forum we use the Epicurean principles and interpret the "why" of pleasure to lead to our goal of the fullness of pleasure. And so we wouldn't agree with some of the points that J. Crago put forth on Epicureanism.
It does seem that Cyrenaic philosophy puts more emphasis on pleasure in the present compared to Epicureanism.
