 In later years, Brentano makes further changes to his theory of time-consciousness. Since temporal modifications can be observed also in mental phenomena that do not contain a judgment (for example when one imagines vividly hearing a melody), he gives up his view that two presentations can differ only in their intentional object and allows for modes of presentation – such as temporal modes. Finally, in a late manuscript that was dictated in 1915, Brentano introduces another minor modification of his theory, suggesting that past objects can be presented only in modo obliquo, while present objects are presented in modo recto.
