‘Be not led by the authority of religious texts, not by mere logic or inference, not by considering appearances, not by the delight in speculative opinions, not by seeming possibilities, nor by the idea: 'this is our teacher’. But, when you know for yourselves that certain things are unwholesome [akusala], and wrong, and bad, then give them up…And when you know for yourselves that certain things are wholesome [kusala] and good, then accept them and follow them.’

from the aṅguttaranikāya, quoted in What The Buddha Taught by Walpola Rahula.
