Alexander, Samuel (1859-1938) Spinoza and Time (1921)
Being the Fourth "Arthur Davis Memorial Lecture" delivered before the Jewish Historical Society at University College on Sunday, May 1, 1929 - Nissan 23, 5681
V. Time as an Attribute of God: Consequences of this Hypothesis
...Thinking things know, they have ideas. The idea of a tree which I have when I see one is for Spinoza the thought-aspect of the bodily condition into which I am thrown by the action of the tree upon my bodily senses. Or as we should say nowadays, it is the inner side of the brain-process. What is a brain-process under the attribute of extension is an idea or thinking process under the attribute of thought. To think of the tree means to have an idea or a bodily process which would be different if the tree were replaced by a table ; and accordingly if for some reason or other this bodily condition recurs in the absence of the tree I still have the tree before my view as an image.
