INTRODUCTION.

and heat are opposed; and fire, which is inseparable from heat, cannot co-exist with cold, or snow, which is inseparable from cold, with heat. Again, the number three excludes the number four, because three is an odd number and four is an even number, and the odd is opposed to the even. Thus we are able to proceed a step beyond 'the safe and simple answer.' We may say, not only that the odd excludes the even, but that the number three, which participates in oddness, excludes the even. And in like manner, not only does life exclude death, but the soul, of which life is the inseparable attribute, also excludes death. And that of which life is the inseparable attribute is by the force of the terms imperishable. If the odd principle were imperishable, then the number three would not perish but remove, on the approach of the even principle. But the immortal is imperishable; and therefore the soul on the approach of death does not perish but removes.
