There are some important yet so far not deeply effectively convincing arguments towards science's legitimacy. Some main ones are:
** theory laddenness i.e it uses concepts such as the sun that its meanings i.e a nuclear burning machine vs disc in sky are ladden to a theory and thereby observation is not theory neautral
** external Sources of reliabibity, not intrrnal: Science belief is justifies iff it is the product of a reliable belief forming process
** induction paradox
