The genitive in this seemingly explicit sentence is not quite clear. One could interpret it – and this would correspond to Friedrich Schiller’s general image – thus: the body constantly, or at least occasionally, attacks the mind. This is something we all know because physical weakness of any kind is what predominantly curbs or frustrates our ability to think. This happens in both childhood and old age and also in between, it is due to physical tiredness, disability and loss of strength – and it is certainly not very pleasant; it leads to constant resistance and to more or less desperate attempts to liberate the mind from the body.
