I agree with the fact that science can't yield all answers. But I think you could expand a little more on the difference between knowledge and wisdom and how each in particular is reached. If meditation provides wisdom by allowing one to escape beyond the physical self then couldn't drugs be argued to have the same effect? What about such instances as initiation ceremonies in which the indivudual enters into a sweat lodge and fasts for a few days then reportedly has a vision and aquires wisdom. Is this true wisdom? or is it knowledge, or neither?
