A few weeks ago we were looking at Laë́rtios 10.135 "In other writings, Epíkouros rejects all divination, as in the Short Epitome, and says 'divination is non-existent – but even if existent: what comes from it ought to be considered nothing to us'"
Along with this statement, we must also consider Torquatus (De Finibus 1.72): "Should [Epíkouros], like Plato, have wasted his days studying music, geometry, arithmetic and astronomy? Those subjects start from false premises and so cannot be true. And even if they were true, they have no bearing on whether we live more pleasantly."
Divination does not exist. However, even if the predictions of diviners were real and sufficiently unambiguous to be actionable – those predictions still could not add anything to our life: because they cannot add to our already existing state of total pleasure (which we already easily achieve by fulfilling our natural and necessary needs).
