If something has to have a certain degree of “faith” to be believed, does that make it to a certain degree: firm belief in something for which there is not 100% proof?
Science requires a certain degree of 'faith' in the processes that it discovers, as well as a certain degree of 'faith' in science itself as a means of understanding the world.
In fact, is there 100% proof that we are all not collectively or individually dreaming, and that science, religion, nature and all of it's laws, etc. are not simply features of that dream? When we sleep at night, are we just dreaming within a dream?
I think it's impossible to get away from a certain degree of 'faith.' Whether that 'faith' or belief is firm or or not is entirely up to the individual practicing his or her 'faith' or belief.
