ANTECEDENT AND EXTRINSICAL NECESSITY.

-------

_J. D._ “Either I am free to write this discourse for liberty against

necessity, or I am not free. If I be free, I have obtained the cause,

and ought not to suffer for the truth. If I be not free, yet I ought not

to be blamed, since I do it not out of any voluntary election, but out

of an inevitable necessity.”

_T. H._ Right Honourable, I had once resolved to answer J. D.’s

objections to my book _De Cive_ in the first place, as that which

concerns me most; and afterwards to examine this Discourse of Liberty

and Necessity, which, because I never had uttered my opinion of it,

concerned me the less. But seeing it was both your Lordship’s and J.

D.’s desire that I should begin with the latter, I was contented so to

do. And here I present and submit it to your Lordship’s judgment.

_J. D._ “The first day that I did read over T. H.’s defence of the

necessity of all things, was April 20th, 1646. Which proceeded not out

of any disrespect to him; for if all his discourses had been geometrical

demonstrations, able not only to persuade, but also to compel assent,

all had been one to me, first my journey, and afterwards some other

trifles which we call business, having diverted me until then. And then

my occasions permitting me, and an advertisement from a friend awakening

me, I set myself to a serious examination of it. We commonly see those

who delight in paradoxes, if they have line enough, confute themselves;

and their speculatives and their practices familiarly interfere one with

another. (_b_) The very first words of T. H.’s defence trip up the heels

of his whole cause; ‘I had once resolved.’ To _resolve_ presupposeth

deliberation. But what deliberation can there be of that which is

inevitably determined by causes without ourselves, before we do

deliberate? Can a condemned man deliberate whether he should be executed

or not? It is even to as much purpose, as for a man to consult and

ponder with himself whether he should draw in his breath, or whether he

should increase in stature. Secondly, (_c_) to _resolve_ implies a man’s

dominion over his own actions, and his actual determination of himself.

But he who holds an absolute necessity of all things, hath quitted this

dominion over himself; and (which is worse) hath quitted it to the

second extrinsical causes, in which he makes all his actions to be

determined. One may as well call again yesterday, as _resolve_ or newly

determine that which is determined to his hand already. (_d_) I have

perused this treatise, weighed T. H.’s answers, considered his reasons,

and conclude that he hath missed, and misled the question, that the

answers are evasions, that his arguments are paralogisms, that the

opinion of absolute and universal necessity is but a result of some

groundless and ill-chosen principles, and that the defect is not in

himself, but that his cause will admit no better defence; and therefore,

by his favour, I am resolved to adhere to my first opinion. Perhaps

another man reading this discourse with other eyes, judgeth it to be

pertinent and well-founded. How comes this to pass? The treatise is the

same, the exterior causes are the same; yet the resolution is contrary.

Do the second causes play fast and loose? Do they necessitate me to

condemn, and necessitate him to maintain? What is it then? The

difference must be in ourselves, either in our intellectuals, because

the one sees clearer than the other; or in our affections, which betray

our understandings, and produce an implicit adherence in the one more

than in the other. Howsoever it be, the difference is in ourselves. The

outward causes alone do not chain me to the one resolution, nor him to

the other resolution. But T. H. may say, that our several and respective

deliberations and affections are in part the causes of our contrary

resolutions, and do concur with the outward causes to make up one total

and adequate cause to the necessary production of this effect. If it be

so, he hath spun a fair thread, to make all this stir for such a

necessity as no man ever denied or doubted of. When all the causes have

actually determined themselves, then the effect is in being; for though

there be a priority in nature between the cause and the effect, yet they

are together in time. And the old rule is, (_e_) ‘whatsoever is, when it

is, is necessarily so as it is.’ This is no absolute necessity, but only

upon supposition, that a man hath determined his own liberty. When we

question whether all occurrences be necessary, we do not question

whether they be necessary when they are, nor whether they be necessary

_in sensu composito_, after we have resolved and finally determined what

to do; but whether they were necessary before they were determined by

ourselves, by or in the precedent causes before ourselves, or in the

exterior causes without ourselves. It is not inconsistent with true

liberty to determine itself, but it is inconsistent with true liberty to

be determined by another without itself.

“T. H. saith further ‘that upon your Lordship’s desire and mine, he was

contented to begin with this discourse of Liberty and Necessity,’ that

is, to change his former resolution. (_f_) If the chain of necessity be

no stronger, but that it may be snapped so easily insunder; if his will

was no otherwise determined without himself, but only by the

signification of your Lordship’s desire and my modest entreaty, then we

may easily conclude that human affairs are not always governed by

absolute necessity; that a man is lord of his own actions, if not in

chief, yet in mean, subordinate to the Lord paramount of heaven and

earth; and that all things are not so absolutely determined in the

outward and precedent causes, but that fair entreaties and moral

persuasions may work upon a good nature so far, as to prevent that which

otherwise had been, and to produce that which otherwise had not been. He

that can reconcile this with an antecedent necessity of all things, and

a physical or natural determination of all causes, shall be great Apollo

to me.

“Whereas T. H. saith that he had never uttered his opinion of this

question, I suppose he intends in writing; my conversation with him hath

not been frequent, yet I remember well that when this question was

agitated between us two in your Lordship’s chamber by your command, he

did then declare himself in words, both for the absolute necessity of

all events, and for the ground of this necessity, the flux or

concatenation of the second causes.”
