In the build-up to Africa Day, I noticed – among others – the slogan ‘I love Africa’ flashing in neon colours that reminded me of music videos seen on MTV in the 1980s. The idea of Africa being loved not only by those living on the continent, but also by the rest of the world, had some moments in the same decade – with pop stars coming together, for example in USA for Africa and the UK version, Band Aid. Although these attempts might have warmed some hearts, it exposed the failure of this kind of sentimentality to contribute much to the continent. Can we think of how to love and engage with the continent in a different way?

Hannah Arendt, in her Thinking journal, contemplated the question, ‘why is it so difficult to love the world.' In response to a letter from her friend and mentor, Karl Jaspers in 1955, in which he wrote to her, “You bring with you shared memories of a lost past. You bring the wide world as it is today,” she wrote “Yes, I would like to bring the wide world to you this time. I’ve begun so late, really only in recent years, to truly love the world that I shall be able to do that now. Out of gratitude I want to call my book on political theories Amor Mundi” (1985: 264). Linked to the idea of loving the world in Arendt’s work, is also that of sharing the world with each other. Arendt famously accused Nazi Adolf Eichmann of refusing to share the world with others. For the purpose of Africa Day on 25 May, I revisited these notions of loving and sharing as reflected by Arendt. I raised the question – what does it mean to love Africa and to share the continent with others?

 For Arendt, the love of the world, and linked to it – the idea of solidarity – is something quite different from equality, care, and sentiment. Love of the world, for her, entails a critical engagement with the world. What could such a love mean in relation to Africa? 

In the prologue to The human condition (1958: 5), she underscores the importance of thought and her concern about thoughtlessness, which she describes as “the heedless recklessness or hopeless confusion or complacent repetition of ‘truths’ that have become trivial and empty”. She sets out that the central theme of the book is to focus on ‘what we are doing’ and that ‘the activity of thinking’ is left out of this work. In other works, Arendt turns to the importance of thinking and, in fact, commentators have noted an ongoing tension in her work between the life of action and the life of the mind. To love the world seems to include both a thorough engagement with what we are doing and a deep contemplation of what it is that we are doing. What has always struck me in her work, is the insistence on thinking and thinking anew each time, instead of merely following what is regarded as ‘truths’. Part of what it could mean to love Africa, is not to accept or repeat trivialities and not to become complacent, but to continuously search for new ways to understand and to respond.

A tension that accompanies the tension between a life of action and a life of thinking, is that between being with others and being alone. Human plurality is for Arendt ‘the basic condition of both action and speech’ (1958:175). Becoming part of the world is like ‘a second birth’ which takes place neither by ‘necessity’ nor by ‘utility’, but by taking ‘initiative’ (177). This birth or new beginning brings forth an ‘unexpectedness’ and ‘happens against the overwhelming odds of statistical laws and their probability’. Where the latter always ‘amounts to a certainty’, new beginnings ‘always appear in the guise of a miracle’ (178). It is by way of action that we become part of the world, share the world with others, and become entangled in the ‘web of relationships’ (181). Of course, for Arendt we always begin again, and the possibility for new ways of doing and forging new relationships is always there. 

Antjie Krog (2015:219) remembers Thabo Mbeki’s speech on the day the Constitution was adopted. “On an occasion such as this, we should, perhaps, start from the beginning. So, let me begin. I am an African. I owe my being to the hills and the valleys, the mountains and the glades, the rivers, the deserts, the trees, the flowers, the seas and the ever-changing seasons that define the face of our native land.” She praises Mbeki for considering the idea of ‘being ruled’ rather than ‘being a ruler’. She finds in his speech a “kind of radical relational enfoldedness with the land” that is vastly different from most discussions from all sides of the spectrum on land. To what extent are those of us living in Africa thinking differently and innovatively, for example about land, and about how we share it with others. How can we think anew about current discourses on the African Renaissance and also decolonisation?

Arendt is clear on the importance of solitude. She underscores the importance of thinking, and slow thinking, and obtaining distance from others, and from the world of action in order to do that. In her way, she was very wary of a certain kind of solidarity based on sentimentality. Engaged citizenship, for her, is always accompanied by a critical self-reflection. Arendt (2003) warned against the urge to act in haste without thinking; she warned against withering ‘under the weight of immediacy’. In a world and a continent with so many dire needs demanding attention and action, this does not mean that we should not act with urgency, but it underscores the importance of well-thought-out responses, of not falling back on old answers.

In short, loving Africa demands of us to engage critically, not to fall back on recipes and formulas, and not to follow rules blindly; it asks us to always begin again; to seek not only for new answers, but also for new questions.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
