I'm in the process of reading Stieners "The Philosophy of Freedom" written toward the end of the 19th century. It was written in German and the translation into english makes it a little hard for me to understand, but somethings that I do seem(?) to grasp to me are interesting.
Heres a link to and part of a clip from chapter 8,,this is the author's 1918 addition made at the end of the chapter which seem a little easier to understand. This is probably to deep of a subject for any one to be dogmatic on but feel free to discuss it, I would be interested in any comments..

Author's addition, 1918
The difficulty of grasping the essential nature of thinking by observation lies in this, that it has all too easily eluded the introspecting soul by the time the soul tries to bring it into the focus of attention. Nothing then remains to be inspected but the lifeless abstraction, the corpse of the living thinking. If we look only at this abstraction, we may easily find ourselves compelled to enter into the mysticism of feeling or perhaps the metaphysics of will, which by contrast appear so "full of life". We should then find it strange that anyone should expect to grasp the essence of reality in "mere thoughts". But if we once succeed in really finding life in thinking, we shall know that swimming in mere feelings, or being intuitively aware of the will element, cannot even be compared with the inner wealth and the self-sustaining yet ever moving experience of this life of thinking, let alone be ranked above it.
It is owing precisely to this wealth, to this inward abundance of experience, that the counter-image of thinking which presents itself to our ordinary attitude of soul should appear lifeless and abstract.
No other activity of the human soul is so easily misunderstood as thinking.
Will and feeling still fill the soul with warmth even when we live through the original event again in retrospect. Thinking all too readily leaves us cold in recollection; it is as if the life of the soul had dried out. Yet this is really nothing but the strongly marked shadow of its real nature -- warm, luminous, and penetrating deeply into the phenomena of the world. This penetration is brought about by a power flowing through the activity of thinking itself -- the power of love in its spiritual form. There are no grounds here for the objection that to discern love in the activity of thinking is to project into thinking a feeling, namely, love. For in truth this objection is but a confirmation of what we have been saying.
If we turn towards thinking in its essence, we find in it both feeling and will, and these in the depths of their reality; if we turn away from thinking towards "mere" feeling and will, we lose from these their true reality.
If we are ready to experience thinking intuitively, we can also do justice to the experience of feeling and of will; but the mysticism of feeling and the metaphysics of will are not able to do justice to the penetration of reality by intuitive thinking -- they conclude all too readily that they themselves are rooted in reality, but that the intuitive thinker, devoid of feeling and a stranger to reality, forms out of "abstract thoughts" a shadowy, chilly picture of the world.
