But Bailey's "hold" has almost a Buddhist sound to it and I would accordingly reject that implication as negative. I would probably add this to my personal list of examples from Bailey where his choice of words reflects poorly on his assessment of Epicurean philosophy.
Does pleasure "hold" us, or does it provide the very goal and reason for living? If Bailey agreed personally with the latter option I don't think he would have used the word "hold" - if he didn't like "engage" and wanted to follow Munro's direction then "keep" or even "sustain" would have been a better choice.
I would see hold here in your sense of keep, something that "holds you up" or "supports you." I don't see hold on this sense as having a negative restraint on you. Consider engage and "hold your attention."
