I believe there is no philosophical high-road in science, with epistemological signposts. No, we are in a jungle and find our way by trial and error, building our road behind us as we proceed. We do not find signposts at crossroads, but our own scouts erect them, to help the rest.
The trouble with our age is all signposts and no destination.Louis Kronenberger
The safest road to Hell is the gradual one the gentle slope, soft underfoot, without sudden turnings, without milestones, without signposts.C. S. Lewis
