Your criticisms of "truth" are not so far off, but you're essentially saying that parts of science are wrong so you can be wrong, too. No actually, you think it is OK to flounder around in the field when you're just starting out. Sure, but not when you don't even know what it is you're supposed to be studying - if anything! This is not analogous to physics, where the general goal was clear from the very beginning: figure out what physical mechanisms underly macro-scale phenomena, such as the hardness of metal, conductivity, magnetic attraction, gravity, etc.

You're just running around to whatever you can grab onto to avoid the main point that there is nothing close to a semblance of delineation of what this "field" is actually about, and it is getting tiresome.
