Supposition Quotes
In fact, for a voluntarist like Schopenhauer, a theory so sanely and cautiously empirical and rational as that of Darwin, left out of account the inward force, the essential motive, of evolution. For what is, in effect, the hidden force, the ultimate agent, which impels organisms to perpetuate themselves and to fight for their persistence and propagation? Selection, adaptation, heredity, these are only external conditions. This inner, essential force has been called will on the supposition that there exists also in other beings that which we feel in ourselves as a feeling of will, the impulse to be everything, to be others as well as ourselves yet without ceasing to be what we are.
Miguel de Unamuno
In the choice of a position, we must pay some regard to the enemy's collected force, and to our divided condition, in which the army must of necessity be cantoned. The enemy now appear to be putting their troops into winter-quarters; but it cannot be supposed they will remain inactive all winter, if we, by the manner of cantoning the army, open to them an opportunity of insulting us to advantage. The mischievous consequences of having our quarters beat up, in the dead of winter, cannot readily be foreseen. That it would be their duty and interest to lay hold of such an opportunity, nobody can deny; and that the character of the General, and many national circumstances, lead to the supposition, must be agreed to. It is necessary, therefore, to take a position which will secure us from a surprise, and have as much force together as possible, to free us from insult. The place where, and the force necessary, to these ends, are the two capital points to decide upon.
Nathanael Greene
If reason (I mean abstract reason, derived from inquiries a priori) be not alike mute with regard to all questions concerning cause and effect, this sentence at least it will venture to pronounce, That a mental world, or universe of ideas, requires a cause as much, as does a material world, or universe of objects; and, if similar in its arrangement, must require a similar cause. For what is there in this subject, which should occasion a different conclusion or inference? In an abstract view, they are entirely alike; and no difficulty attends the one supposition, which is not common to both of them.
David Hume
