Again, after the chicken is hatched, it grows more feathers and bones and blood, but we still say that it knows nothing about all this. What then do we say it _does_ know? One is almost ashamed to confess that we only credit it with knowing what it appears to know by processes which we find it exceedingly easy to follow, or perhaps rather, which we find it absolutely impossible to avoid following, as recognising too great a family likeness between them, and those which are most easily followed in our own minds, to be able to sit down in comfort under a denial of the resemblance. Thus, for example, if we see a chicken running away from a fox, we do admit that the chicken knows the fox would kill it if it caught it. On the other hand, if we allow that the half-hatched chicken grew the horny tip to be ready for use, with an intensity of unconscious contrivance which can be only attributed to experience, we are driven to admit that from the first moment the men began to sit upon it—and earlier too than this—the egg was always full of consciousness and volition, and that during its embryological condition the unhatched chicken is doing exactly what it continues doing from the moment it is hatched till it dies; that is to say, attempting to better itself, doing (as Aristotle says all creatures do all things upon all occasions) what it considers most for its advantage under the existing circumstances. What it may think most advantageous will depend, while it is in the eggshell, upon exactly the same causes as will influence its opinions in later life—to wit, upon its habits, its past circumstances and ways of thinking; for there is nothing, as Shakespeare tells us, good or ill, but thinking makes it so.
