Hey Rogue Red I have your chart here. 2 points...
1) I must be lacking a font or something, as the chart you gave me was full of *%$4^6%;pP:8#}{&^%&)(£"FD£$G (not swear words.)
2) I did you chart on astro and thought this:
You're right, there is very little air here. I would say moon on 11th cusp is closest I can get and Mars near 3rd house cusp. There's this Venus-Mars interplay, the mutual reception, joint final dispositors, Venus in the Mars house, Mars in the Venus house. You also have Saturn in the 1st- it co-rules this house but this is also the house of its fall. Sun exalted in Aries, but falls in 2nd house, a good leeway between Venus and Mars.
So if I was to explain your comments using your chart where would I start?
I would look at the thought houses- 3 and 9, and see that they are ruled by Venus and Mars, the co-rulers of your chart. This would make these houses very important for you. But the energy is focused onto the 1st and 2nd houses, so the thinking might be primarily about yourself, your growth, what you would like to learn. The thinking is more integrated, and although it is not airy, it is highly personal. Besides, if you take Pluto as the 8th ruler and not Mars, it is conjunct Uranus, giving a more Uranian flavour to the 9th house process. And the Asc ruler itself in the 9th house which is a very good sign for thought of the type you describe. Having Neptune, Pluto and to a lesser degree Uranus involved in the 9th house gives you kudos in this area.
I would say moon 11th house cusp, but this would only work if there were other people present- friends etc. The moon in Capricorn would give a serious tone, but this would eventually work out into good intellectualism, as moon trines Uranus, and was inspired by Neptune. There is also the square to sun and more widely Mercury. Do you think this means your emotional need to be in a social circle, to chat with others, is at odds with a desire to really express the things you value? I think Cancer and Capricorn are intercepted here, which makes them frustrated, so this moon need might not be met- here it would contradict the sun and the 11th house, which is ruled by Aquarius with Uranus in the 6th.
I might also suggest, if you think you are in a constant barrage of thoughts and words, that Mars might be on the cusp of the 3rd, but you said it is less about this and more about internal and quiet thought. This would relate more to the Saturn, as well as Neptune in the 9th.
Lastly I would say Mercury trine Jupiter always gives an intellectual and reflective slant- especially the reading and observing.
So we have three things here- the Venus-Mars personalised thinking energy, incorporating the Neptune and Pluto, the moon in 11th- 'the emotional need to converse, but may conflict with more important matters such as the things you value', and lastly the Mercury-Jupiter trine, which with the retrograde, and the node nearby, forms a neat little fiery intellectuality. Of these I think the moon might be the weakest.
That you are pre-occupied with this so much might show you are more in tune with your node and these parts of your chart. So you will find growth in these aspects, to think about your 2nd house.
I hope that might make sense, even though there is no air in your chart. I think this means your thoughts and thinking style are more atypical, rather than that you don't think, as everyone has to think. And fire is also intellectual in it's own way, in a broader way. With Neptune in the 9th and Venus ruling the 2nd I would also have to ask you what your thinking style actually is, and if it is infused with a more fire imagination, vision and sensuality rather than the typical air type rationalism and detail.
PS
I'd love to know what you think about your moon. It might be a good example of what I was writing about earlier, about how the sun or moon or Asc are sometimes overridden by other planets. Here it is in Capricorn and is intercepted in the 10th house, but is on the cusp of the 11th without Capricorn ruling the 11th. So it appears to be frustrated in all directions, with a square to the sun! It also doesn't fit in with the fiery Venus and the heavy sensuality of Taurus, and those are the planets I looked at first.
