 Husserl has provided no good or even meaningful reason for doubting that the natural world exists, however much that existence may also have been ‘constituted’ or rather reconstituted for out minds, and that its processes have an important causal relation to the acts of constitution just mentioned, being in fact responsible for the ‘fulfilment’ of those acts through appropriated data, and that natural objects are increasingly given as they are in and for themselves, in an unbracketed and not merely bracketed sense, both through the normal perceptions of men and the theories of the less methodologically prejudiced scientists.
