Assuredly, rejection means control of one's thoughts, and why should not one be master of one's own mind and thoughts and not only master of one's vital passions and bodily movements? If it is the right thing to control the body and not allow it to make a stupid, wrong or injurious movement, if it is the right thing to reject from the vital an ignorant passion or low desire, it must be equally the right thing to reject from the mind a thought that ought not to be there or that for good reasons one does not want to be there. As for possibility, I suppose when a thought that is manifestly stupid or false presents itself to the mind one can and usually does reject and throw it out and bid it not recur again. If one can do that with a given thought, it follows that one can do it with any thoughts that need for any reason to be excluded. If a scientist goes into his laboratory to work out a problem, he shuts out from his mind for the time being all thoughts of his wife, his family or his financial affairs, and if they come he repels them and says, "This is not your time." If he has resolved to carry out a line of investigation to the end or a method of invention and, if doubts assail him, he will certainly throw them aside and say, "I mean to see this through to the end and till I have reached the end, I have no intention of listening to you." At every step a man of any mental calibre has to exercise some power over his mind, otherwise he would be as much in a state of restless mental confusion or of mechanical incoherence as one who had no control over his impulses and desires.
