When you take a sharp catch - a slip catch at cricket, for example - is it something you really do? The question is Raymond Tallis's. He describes the various components of bringing off a catch successfully:
First of all you had to ensure that your hand and the ball intersected. This required an instantaneous selection of your final position and posture, so that you could set your flying body's trajectory to that position. You would also have to make sure your arm unfolded the right amount, moving, like your body, at the right speed. Mere intersection would not be enough: the posture of the hand has to be predetermined. If the hand is not open wide enough, the ball will never get bedded in: it will bounce off, leaving you with a sore fist. If the hand is open too wide, the ball will slip out, and you will have to bear the dual crosses of a stinging palm and a disconsolate bowler. But this is not all you have to get right. The moment the ball makes contact, the open hand of welcome has to turn into a barricade of digits moving in precise formation to turn the new arrival into a captive. What's more, the handy work of the snatch squad has to be made easier by ensuring that the stiffness or impedance of your arm is precisely gauged. If the impedance is too high, and you present a brick hand, the ball will bounce out before the cage door can close. If the impedance is too low, the ball will brush your hand aside. More precisely, there has to be a continuous alteration of impedance before and after the impact. And there are many other variables that have to be controlled of which you are not even dimly aware.
On this basis, Tallis asks if making a catch - among many other actions - is more a 'happening', a collection of 'mechanisms', than it is a truly voluntary action. Can we really be seen as the authors of actions of which we 'do not intend most of the components'? Tallis's
answer to the question appeals to the whole background of intentionality that enables anyone to complete a particular catch successfully: taking up cricket, practising the game, agreeing to participate in this specific match, making the necessary arrangements, turning up on the day. As you can work out for yourself, there's even more. There's the fact that the slip fielder positions himself appropriately, knows just when to be in a state of maximum readiness, has learned how best to minimize distractions to his concentration at that moment. In any case, Tallis invokes this broad context of intentions to affirm that it is the catcher who is indeed the author of the act of catching the ball. The catch isn't just a happening or combination of mechanisms.
The slip fielder carries out a vast number of voluntary actions to enable himself to perform that magnificent catch effortlessly and virtually without volition.
I think one can go further, however. The volition is there not only in the background of intentionality; there's intent even in the tiny instant of time in which the catcher brings off the catch. The way to see this is by thinking about when, prior to completing the catch, he could deliberately decline to do that. And the answer is:
at any time. Making a snap decision to fail, he could let the ball brush past or burst through his fingers, let it bounce out of his hand(s), or what have you. If an intention to fail can intervene right up to the very last split second, then the intention
not to fail is operative (at least usually) when he succeeds.
