Plotinos: Complete Works, v. 2 In Chronological Order,...

Likewise it is men too weak for speculation who, in action, seek a shadow of speculation and reason. Not being capable of rising to speculation, and because of their soul-weakness not being able to grasp that which in itself is intelligible, and to fill themselves therewith, though however desiring to contemplate it, these men seek, by action, to achieve that which they could not obtain by thought alone. Thus we find that action is a weakness or result of contemplation, when we act, or desire to see, or to contemplate, or to grasp the intelligible, or try to get others to grasp it, or propose to act to the extent of our ability. It is a weakness, for, after having acted, we possess nothing of what we have done; and a consequence, because we contemplate something better than we ourselves have made. What man indeed who could contemplate truth would go and contemplate its image? This is the explanation of the taste for manual arts, and for physical activity183 (as thought Aristotle).
