Clearly, there is something wrong withthe thinking of modern Man: I think we can agree about that - but what should be done about it?
Many mystical/ spiritual people are set against thinking, as such - they regard thinking as the basis of illusion (maya) and alienation, and therefore they try to stop thinking.
Stop thinking and just be is the kind of advice.
The most usual method recoemmended is practicing some method of meditation.
But (unfortunately) for modern people the most easy and direct method of stopping thinking is intoxication; which is probably why the Eastern spiritualities of the Beatnicks and Hippies swiftly became drugs-orientated.
So; if stopping thinking is the ideal, then methods such as intoxication, deep sleep (or anaesthesia) are the most reliable methods; and death (i.e. suicide) is the most permanent. Suicide (or attempts at suicide) is not all that unusual among those who seek not to think - and suicide is made much more likely by most types of psychoactive drug usage.
The great breakthrough of Rudolf Steiner, in his first four books culminating in The Philosophy of Freedom, was that our proper goal should be almost the opposite: he argues that we need to trust our thinking much more fully than we do at present - and to strengthen and expand thinking.
One point is that if we mistrust our own thinking, we deal a deadly blow to ourselves - consciousness becomes alienated from our selves (our true and divine selves), as well as from the world. If we cannot trust thinking, we cannot trust anything - since everything we know comes through thinking.
The task is therefore ultimately to ensure that our thinking is trust-worthy - and in the meanwhile to learn to distinguish trust-worthy thinking from the kind of thinking that is not trustworthy (which is - for most people, most of the time - our ordinary everyday thinking, which we know from experience has something wrong with it).
I have termed this trust-worthy thinking Primary Thinking - and regard it as our consciousness of the real self; our awareness of God-within-us; an experience of the divine way of Being, in which a god knows explicitly, and is therefore able to be free.
(Since un-conscious knowing is not free.)
This idea of Steiner's was - I think - something new under the sun!
Instead of regarding the thinking Ego as The Problem which ought to be deleted; we regard thinking as The Answer.
We should try (as it were) to go through the Ego and out the other side. By which I mean that we ought to regard Primary Thinking as potentially a higher form of consciousness than either divine Ego-less hence unconscious Being on the one hand; or the mainstream modern state of alienated, solipsistic, relativistic and despairing consciousness.
The intent is that by strengthened and expanded thinking we should become aware of the divine that was previous unconscious to us; and therefore become able to join with the divine work of creation - rather than being unconsciously immersed-in and swept-along-by the divine.
And one consequence is that our persepctive becomes pro-life. Fantasies of disovering the truth by not being fully human - by deletion of thinking through meditation, intoxication, or death - are replaced with an imagied future in which our thinking is as powerful as our instincts and emotions; and expanded to includes all that is deepest and best: the spiritual as well as the material.
