In a wide-ranging, philosophically oriented discussion of nervous activity, Brownian motion, genetics, and other "ultramicroscopic" phenomena in organisms, Lillie suggested that quantum indeterminism "would conceivably explain the indeterminism or inner freedom seen in voluntary action ..." (57) For his part, Compton noted that indeterminacy at the quantum level would lead to unpredictable initial conditions formacroscopic events within organisms, as a nerve pulse at the molecular level is amplified many times.
