Quote by Wilhelm Wundt
From the standpoint of observation, then, we must regard it as a highly probable hypothesis that the beginnings of the mental life date from as far back as the beginnings of life at large.
Summary
This quote suggests that based on observational evidence, it is highly likely that mental life began at the same time as the emergence of life itself. In other words, the origins of conscious experience can be traced back to the earliest stages of life's existence.
