Hannes Alfven

The difference between myth and science is the difference between divine inspiration of `unaided reason' on the one hand and theories developed in observational contact with the real world on the other. [It is] the difference between the belief in prophets and critical thinking, between Credo quia absurdum [I believe because it is absurd--Tertullian.] and De omnibus est dubitandum [Everything should be questioned--Descartes.]. To try to write a grand cosmical drama leads necessarily to myth. To try to let knowledge substitute ignorance in increasingly large regions of space and time is science.
