"2. That these differences may be due not only to the degree of thought intensity, but also to the nature of the thought itself, according as it is visual, auditive, or motor.
"3. That some account has to be taken of a sort of accord, of concordance between the two intelligences.
"4. That excessive will-power impairs the definiteness of the transmission without much enhancing its intensity.
"5. That strong, persistent, prolonged thinking of a thought repeated for a longer or shorter time constitutes a condition in the highest degree favourable.
"6. That any distraction which causes the thought to disappear for a moment, or that makes it cease to be isolated, seems eminently unfavourable to the mental action.
"7. That, nevertheless, thoughts that are not intense, and even thoughts that are at the moment unconscious (subconscious), may be transmitted involuntarily.
"8. That the muscular efforts which usually accompany an exertion of will are more or less indifferent; but that the muscle expression of the operator may be useful, subjectively, by reason of the habitude that connects thought with these expressional signs.
"It follows from these considerations that the operator should insist less upon the 'I will it' than upon the content of that willing; and hence it is probable that, properly speaking, it is not the 'strong will' that helps telepathy so much as clear thinking."
As to the subject or percipient, experience has taught us that the four following states are probably the most important for the recipience of a telepathic message:
1. In the state of profound aideia (complete lack of thought) transmission is never immediate, but it may sometimes be latent.
