 Thought. I use this term to include everything that is within us in such a way that we are immediately aware [conscii] of it. Thus all the operations of the will, the intellect, the imagination and the senses are thoughts. I say ‘immediately’ so as to exclude the consequences of thoughts; a voluntary movement, for example, originates in a thought. (CSM II 113 / AT VII 160; cf. Principles of Philosophy Part I, §9 / AT VIIIA 7–8)
