Based on the commentary of the Akeidas Yitzchok we can say the following. We observe in nature that the more sophisticated a creature, the more fragile is its physical composition. On the other hand, if something appears to be of very durable construction, its function and potential is simple and uncomplicated. Stones are durable, their impact on, and contribution to life is minimal. Humans are extremely fragile organisms, but their potential and actual impact on life on this earth is tremendous.
Brute strength equals unattractive form or packaging.
We observe simple insects such as ants, able to build for themselves elaborate homes, storage facilities, etc. Powerful animals such as lions, on the other hand, are unable to make provisions for themselves. Their bodies seem exposed to all kinds of danger. Farmers, usually possess a physique that enables them to achieve survival in a struggle with the elements, whereas the scholar usually seems quite weak, unable to cope with the challenge of physical survival in this world. It is further interesting to note, that things which are physically strong and intellectually weak, do not disintegrate completely after they have ceased growing.
