The Buddhism holds that truth – especially religious truth – is something that everyone has access to and of which no one has monopoly. It could be understood by everyone for himself. The Buddha did not believe in distributing ready-made transcendental wisdom for everyone. He wanted people to get at the Dhamma by themselves (paccattam veditabbo). When someone presented a theory the Buddha would naturally ask him “Do you know and see this yourself?”.
