Some people are concise, other use many words. As I tend to take a question seriously, I usually end up in the second category. In the below, I’d would like to just share what immediately springs to mind when reading your question. I write them here as an un-edited train of thoughts, and will try to tweak, structure or expand on this in further edits. I apologize in advance if it becomes lengthy once I’m on a roll. So here goes.
Many angles of thought come up when considering your question, they are like different streets we could walk into and explore
1) First, when we use the word science, we are very much stuck by habit to what the word means in today’s world with physical mineral science. So it’s worthwhile to first develop a good understanding what the term encompasses, as in the scientific method and epistemology.
Rudolf Steiner describes this by juxtaposing the current scientific method as originating with Bacon, versus Goethean science. The philosophical underlying foundations show a similar duality with Kant (current mineral science) vs Hegel (who includes the observer and consciousness experience). This insight is quite important as it’s foundational for the discussion. See also Top five problems with current science and Relationship between mineral and spiritual science.
It would carry us to far here, but a related aspect is to understand how science paradigms work, and the limits of any knowledge framework or representation (eg Popper, Kuhn etc).
2) That being said, we cannot transpose the way how our current mineral science works to spiritual science, plainly because of the nature of the beast (see also Cosmic fractal). It's different. The spiritual reality is not like the mineral, like physical matter. The senses, the dimensionality, it just does not work like in space and time, as we experience it with another type and quality of consciousness. This is a big step to take. Because one may want to have expectations to re-apply or have the same way of working in the spiritual as in the mineral science, but that is not possible. That is why Rudolf Steiner explicitly did not want to work with definitions, why he opposed simple summaries, etc. Another street or alley we could explore and expand on.
A good place to start here practically is the 'Notes on the study process' on Tools and practical site info#About the study process and working spiritual science.
From the above follows immediately that a major challenge lies in the translation, the mapping into our mundane language, what one experiences. Challenge one is to have a balanced faculty (see next point), the second is the ability to retain the experience in consciousness and translate it for re-use. More on this below.
3) A.P. Shepard wrote a booklet whereby he called Rudolf Steiner the ‘scientist of the invisible', and Steiner himself used the terms theosophy and anthroposophy, but also spoke of this as spiritual science. He used this term for good reason, because as a trained scholar he wanted to have the spiritual worldview being taken seriously.
In today’s modern world, the rigour of a scientific approach is welcome and needed as a protection to much hot air and waffling about the spiritual. Already in Steiner’s time theosophists came up with a materialistic version of the truly spiritual (eg Leadbeater book on the atom, etc), there was the wave of ‘spiritism’ in the 19th century. In the 20th century we got ‘new age’ spirituality, etc. .. people have a hard time making the distinction between the truth and genuine valuable sources and the mass of nonsensical information that is available and growing every instant. We could go down this street covering this differentiation. Discernment is an important spiritual faculty of the consciousness soul.
And briefly on repeatability and consistency.
- Because in the spiritual the human being microcosm is an integral part of the macrocosm, the apparatus for experiences, experiments and reporting is our Personality and Individuality with its specific elemental balance (in structure and make up). An example of repeatability is illustrated with Schema FMC00.487. Spiritual initiation exercises provide a clear description of the goal that needs to be reached before moving on to the next exercise. That way one gets a broad gradient or metric for progress along spiritual development. Thousands of people worldwide are following this system, the schema just shows a small sample of more then 20 years ago. The system works, and since then many forums and books have seen the light.
- The element that struck me as crucial from the beginning is consistency. What makes the spiritual a science is that numerous sources over millenia have reported on the spiritual reality in a consistent way. The consistency is there over and above the changes in languages, culture and consciousness. There have always been four elements, not three, and similarly independent cultures and clairvoyants have talked about the higher worlds, the spiritual hierarchies, threefoldness, unity and love, etc. So one thing that Rudolf Steiner tried to do is to show how all these hang together and how also ancient myths, symbols, remnants of ancient cultures, are all consistently about the same spiritual realities. Today we just have a certain stage of intellectual development and consciousness and thus use a certain language, but people throughout the ages have used many languages, be it alchemy or parabels, symbols or sigils.
An image I like using is that of a bandpass filter: depending on our state of consciousness and spiritual development, we look at reality through different glasses. It’s a statistical phenomenon, like a normal Gauss curve along an axis of spiritual maturity for the whole of humanity: the majority sees only matter with physical senses, but a minority experiences more, and a trained advanced minority is at home in the higher worlds. That resolves the dichotomy for discussions on pseudo-science like on Wikipedia.
4) Initiation. Personally, I am of the opinion that is not sound or healthy to have one’s brain full about spirituality, if one does not live it, and does not practice it. This is not my opinion alone, with this I am merely following spiritual teachers who have said the same, quite consistently. The quote 'An ounce of practice is better than tons of theory' captures it succintly, but there are numerous quotes in this sense.
Spirituality is about ourselves and our world, our role in the world, and how we stand and live in that world .. based also on what we believe ourselves and this world to be, really. It’s not dry information or dead knowledge, it’s a way of living, how we stand in the world - the conscious free choices and actions we take. See also Seeds for future worlds
From personal experience, therefore a key step is if one commits to practice of spiritual initiation exercises (such as in Rudolf Steiner’s Knowledge of the Higher World and/or Franz Bardon’s IIH book). To commit means to take this on as a hobby, freely, as a daily discipline and priority. If one does so, one balances the intellectual study (a crucial balancing), and (of course depending on spiritual maturity and karma), one will live the reality of what spiritual concepts are all about. This is absolutely key. In weeks, months and years, one can/will experience vacancy of mind and realize one’s own consciousness without sensory impression or thought, feel experientially how the body breathes the etheric energy through pore breathing, one will sense what’s happening to one’s chakras as one practices consistently over the years, be able to steer the energy flows and work with the elements. And all this is just the start, I’m just trying to make the point: what one knows from experience, one no longer needs to believe. So if one includes in one’s daily practice the praying, for example of the Lord’s Prayer, then this will develop into something that no written book experience will be able to compare to. It’s the difference between the ‘living’ version and the ‘dead’ version.
I believe this is an essential point and its importance cannot be underestimated.
5) Different profiles. When talking about spiritual science, one has to appreciate that it’s such a broad area that there is no simple singular answer that fits all. Some people are or will develop, due to their Individuality (and karma), to initiates who are fully experiential but not scholars at all (for example Rawn Clark says this of himself). Again Rudolf Steiner kept different lectures to describe the differences: scholar, initiate, magician, clairvoyant, .. .
Others will develop the capability of clairvoyance, but definitely not everyone will develop this. Also important: if the development was not balanced but faculties came like unpolished innate, some people have faculties from which they can report, but that are not always correct or truthful because overly coloured with personal skewing due to the unbalanced development of the person. That is why we get such wide spectrum with lots of nonsense in it also, people may be very honest in reporting their experience, but it doesn’t mean their experiences are truthful along the criteria of the spiritual scientific method. The latter requires brutal honesty, discernment, conscientiousness as part of initiation and working on one’s self. Unfortunately souls with good intentions can be quite misguided.
Furthermore, this connects to what I wrote above .. it’s one thing to have an experience in a higher state of consciousness that is clear and truth (and not coloured by one’s own lack of elemental balance), it’s another to be able to be able to bring that down to mundane waking consciousness as a ‘report’ or some description that makes sense or is meaningful for people who have not had the experience. You sense rightaway this part is not quite immediately in reach for everyone (though with years and decades everyone can and will progress, either in this life or in future ones .. work on initiation exercises does not get lost but carries over in terms of spiritual maturity).
On the side, the level of clairvoyance that Rudolf Steiner spoke from is very rare, and there are good reasons why his contribution is unique and beyond what a typical person can reach. This has to do with his mission, the White Lodge, and would lead us too far here.
However usually the more advanced and wise a person gets, the less he/she comes into the public as this is not always their karmic mission. So there are adepts who are extremely advanced, but publicly unknown, as they work in the higher worlds (and ‘behind the scenes’ so to speak). Much and most of the spiritual is therefore not only in what one would call the working on and spreading of the spiritual (scientific) worldview in our world.
6) Whereas under 4) I made the point that one cannot truly live the spiritual and not work on one’s self, it is not so that one needs to have developed spiritual faculties to contribute to the spiritual scientific worldview. Rudolf Steiner explained this on many occasions, you'll also find them on this site.
- A first good illustration comes from people who have used the Goethean scientific method (see eg Bortoft) of pure observation, linking it to possible hypotheses and descriptions. One can train one-self in this also.Many examples exist, eg people who worked on metamorphosis in the plant and animal kingdoms, eg. Frits Hendrik Julius would be a nice example).
- A second illustration would be the work done on the etheric in the plant kingdom: we have a theory, mathematical models, and one can experientially check this in various way (eg alchemy, but also Bardon’s IIH exercises allow to know from experience these influences of the elements and ethers). A very nice example is Lawrence Edwards who studied buds and linked the experiential data to the mathematical model for the theoretical frame laid out by Rudolf Steiner (re his book 'vortex of life'). Another example would be the work of Lily Kolisko (see more here) who proved scientifically the working of the etheric influences from the different planetary spheres, the effect of potentization underlying homeopathy.
From this angle we come into the areas of application such as agriculture, medicine etc. It does not have to be initiation, alchemy or white magic that one needs to work on and contribute to the spiritual scientific worldview.
7) Last, it speaks for itself that, if one wants to contribute to the spiritual scientific worldview, there are countless opportunities. Examples are all those who have worked in the last century in the streams of anthroposophy, theosophy, initiation, people who have worked on dissiminating the information available (see ao Navigating anthroposophical resources), adding from personal experience, and from study (see also for example systematic anthroposophy), also bridging the current science with the spiritual scientific worldview, those who worked on the border between belief systems, who furthered the application areas (eg waldorf schools, biodynamic agriculture, etc).
This is also about 'why are we doing this'. One's personal mission usually follows naturally from the path followed. This small website initiative is an example .. the goal is to lower the threshold and make structured info available broadly, so it can help others along the path. It's quite natural we are there to be of meaning and support for our brothers and sisters. Thus you will find so many genuine initiatives, each person is just contributing in their own way.
Well it has become a lengthy response, I hope the various angles of perspectives may be useful for background. I included some pointers and links to other topic pages in case you'd be interested to explore, but of course there's more and I'd be happy to go down any of these streets (sketched above) further with you, or others in case you want to home in differently from your starting questions.
