English is intended to help students develop the critical abilities they need at the college level. Although the content of various sections vary somewhat, all emphasize writing skills and reading comprehension. Moreover, individuals caught up in this greater drama have shared the insights of their individual journeys through oral and written expression. In this way, voices of past and present adversities pass on individual experiences of downfall and victory, folly and wisdom, anguish and hope as fertilizer for the enrichment of others.
In casual encounters with the material universe, we rarely feel any difficulty here, since we usually deal with things that are clearly alive, such as a dog or a rattlesnake; or with things that are clearly nonalive, such as a brick or a typewriter.
Nevertheless, the task of defining "life" is both difficult and subtle; something that at once becomes evident if we stop to think.
Consider a caterpillar crawling over a rock. The caterpillar is alive, but the rock is not; as you guess at once, since the caterpillar is moving and the rock is not. Yet what if the caterpillar were crawling over the trunk of a tree?
The trunk isn't moving, yet it is as alive as the caterpillar. Or what if a drop of water were trickling down the trunk of the tree? The water in motion would not be alive, but the motionless tree trunk would be.
It would be expecting much of anyone to guess that an oyster were alive if he came across one for the first time with a closed shell.
Could a glance at a clump of trees in midwinter, when all are standing leafless, easily distinguish those which are alive and will bear leaves in the spring from those which are dead and will not?
Is it easy to tell a live seed from a dead seed, or either from a grain of sand? For that matter, is it always easy to tell whether a man is merely unconscious or quite dead? Modern medical advances are making it a matter of importance to decide the moment of actual death, and that is not always easy.
Nevertheless, what we call "life" is sufficiently important to warrant an attempt at a definition. We can begin by listing some of the things that living things can do, and nonliving things cannot do, and see if we end up with a satisfactory distinction for this particular twofold division of the Universe.
A living thing shows the capacity for independent motion against a force. A drop of water trickles downward, but only because gravity is pulling at it; it isn't moving "of its own accord.
Living things that seem to be motionless overall, nevertheless move in part.
An oyster may lie attached to its rock all its adult life, but it can open and close its shell. Furthermore, it sucks water into its organs and strains out food, so that there are parts of itself that move constantly.
Plants, too, can move, turning their leaves to the sun, for instance; and there are continuous movements in the substance making it up.
