From what I understand from the introduction of what Bachelard does, he is trying to relate philosophy to science. He is actually considering the science from a philosophical standpoint and considering their implications. Sciences on a whole is still subjective as much as people like it to be objective. People only do experiments that they want to know and if value is not seen in it then there is no point in experimenting in it. However the opposite is also true where there are a number of scientific research papers that are just obsolete since the research is done yet no one uses then. He seems to emphasis on the poetic image which has no time and is spontaneous, a concept which i don’t quite understand, due to the fact that to me images are a result of a person’s experience and whatever thoughts or images we feel right now is a result of time and the result of our cognitive abilities.
