  Another problem for the Revisionist concerns Owen 1965’s proposal, adopted by Bostock 1988, to redate the Timaeus to the Middle Period, thus escaping the conclusion that Plato still accepted the theory of Forms at the end of his philosophical career. The trouble with this is that it is not only the Timaeus that the Revisionist needs to redate. In quite a number of apparently Late dialogues, Plato seems sympathetic to the theory of Forms: see e.g., Philebus 61e and Laws 965c.
