Hume does the same thing with causation. It is known as habitual antecedence, and as tendency on our part to look for something definite to come. Apart from this practical meaning it has no significance whatever, and books about it may be committed to the flames, says Hume. Dugald Stewart and Thomas Brown, James Mill, John Mill, and Professor Bain, have followed more or less consistently the same method; and Shadworth Hodgson has used the principle with full explicitness. When all is said and done, it was English and Scotch writers, and not Kant, who introduced "the critical method" into philosophy, the one method fitted to make philosophy a study worthy of serious men. For what seriousness can possibly remain in debating philosophic propositions that will never make an appreciable difference to us in action? And what could it matter, if all propositions were practically indifferent, which of them we should agree to call true or which false?
An American philosopher of eminent originality, Mr. Charles Sanders Peirce, has rendered thought a service by disentangling from the particulars of its application the principle by which these men were instinctively guided, and by singling it out as fundamental and giving to it a Greek name. He calls it the principle of PRAGMATISM, and he defends it somewhat as follows:[297]--
[297] In an article, How to make our Ideas Clear, in the Popular Science Monthly for January, 1878, vol. xii. p. 286.
Thought in movement has for its only conceivable motive the attainment of belief, or thought at rest. Only when our thought about a subject has found its rest in belief can our action on the subject firmly and safely begin. Beliefs, in short, are rules for action; and the whole function of thinking is but one step in the production of active habits. If there were any part of a thought that made no difference in the thought's practical consequences, then that part would be no proper element of the thought's significance. To develop a thought's meaning we need therefore only determine what conduct it is fitted to produce; that conduct is for us its sole significance; and the tangible fact at the root of all our thought-distinctions is that there is no one of them so fine as to consist in anything but a possible difference of practice. To attain perfect clearness in our thoughts of an object, we need then only consider what sensations, immediate or remote, we are conceivably to expect from it, and what conduct we must prepare in case the object should be true. Our conception of these practical consequences is for us the whole of our conception of the object, so far as that conception has positive significance at all.
This is the principle of Peirce, the principle of pragmatism.
Such a principle will help us on this occasion to decide, among the various attributes set down in the scholastic inventory of God's perfections, whether some be not far less significant than others.
If, namely, we apply the principle of pragmatism to God's metaphysical attributes, strictly so called, as distinguished from his moral attributes, I think that, even were we forced by a coercive logic to believe them, we still should have to confess them to be destitute of all intelligible significance. Take God's aseity, for example; or his necessariness; his immateriality; his "simplicity" or superiority to the kind of inner variety and succession which we find in finite beings, his indivisibility, and lack of the inner distinctions of being and activity, substance and accident, potentiality and actuality, and the rest; his repudiation of inclusion in a genus; his actualized infinity; his "personality," apart from the moral qualities which it may comport; his relations to evil being permissive and not positive; his self-sufficiency, self-love, and absolute felicity in himself:--candidly speaking, how do such qualities as these make any definite connection with our life? And if they severally call for no distinctive adaptations of our conduct, what vital difference can it possibly make to a man's religion whether they be true or false?
For my own part, although I dislike to say aught that may grate upon tender associations, I must frankly confess that even though these attributes were faultlessly deduced, I cannot conceive of its being of the smallest consequence to us religiously that any one of them should be true. Pray, what specific act can I perform in order to adapt myself the better to God's simplicity?
