Statement

The person of science realizes that the only reality for them is their own self, and that the only real world is the world as their sensations give it to them. That’s why, instead of following the fallacious path of adopting their sensations to other people’s, they use objective science to try to achieve a perfect knowledge of their world and their personality. There’s nothing more objective than their dreams, and nothing more infallibly theirs than their self-awareness. Around these two realities they refine their science. It’s very different from the one practised by the old scientists, who, rather than studying the laws of their own personality and the organization of their dreams, sought the laws of the ‘outside’ and the organisation of what they called ‘Nature’.
