I think what I'm trying to say is that, without the craft practised ages past, would science be what it is today? The practitioners of the craft laid the foundations for study and experimentation. The knowledge gleaned was then carried forward and as time passed it formed into branches or disciplines that eventually we now recognise today as science.
Having said all that, we still have witchcraft today, There are aspects that science simply can't explain away, or to quantify. Is it because its too "daft" to be studied fully? Why IS witchcraft still around? is it for traditionalists to practise? Of course not. Its because witchcraft still works and is still real and very much alive. It can do things that science can't. I don't know enough about the craft to be able to illustrate but I'm sure we have witches here who could explain it better than I.
OR could it be that witchcraft is physics in its basic form? The craft is the ability to manipulate the natural order of everything, ideally for beneficial reasons, whereas Physics, being the study of everything is too busy studying what it is rather than what it can do.
One thing I have neglected to mention in all this, is the religious aspect. Yes, Paganism is a religion and we worship the Divine in many aspects, and dependant on what tradition we follow we do so in our own ways. Science having advanced so far has forsaken a Divine entity in favour of tangible evidence. Do scientists not worship at the church of the laboratory however? their Athame is the laser. their burning bowl is the crucible and their candle, the bunsen burner.
Physicists are in fact searching for that single - thing? entity? - that brings everything together, therefore they are in fact, Seekers.
