There's the brain-ache of attempting to force thought into existence, into a form recognisable in language (or image, or music, or dance). I was tempted to put the word 'new' before thought, but I fear that 'new' can be something of a weasel word, perverting, distorting, distracting. After all it might be just as valuable to rediscover an old thought. At the same time we (humans) do need to find (new?) solutions, to give birth to those thoughts that move us towards the paradigm shifts that will enable us to, for example, remake our world in conformity to evolving ecological concerns; to manage a better balance between egalitarianism and individual freedom.
There is the push in me to think, to grapple, to struggle . . . but then a doubting thought intervenes: well, what difference will my little bit of thought make? Why not leave it up to them? The big guns, those gifted with great minds.
